There are certain crates which we re-export within `types` which creates a fragmented DevEx, where there are various ways to import the same crates.
```rust
// consensus/types/src/lib.rs
pub use bls::{
AggregatePublicKey, AggregateSignature, Error as BlsError, Keypair, PUBLIC_KEY_BYTES_LEN,
PublicKey, PublicKeyBytes, SIGNATURE_BYTES_LEN, SecretKey, Signature, SignatureBytes,
get_withdrawal_credentials,
};
pub use context_deserialize::{ContextDeserialize, context_deserialize};
pub use fixed_bytes::FixedBytesExtended;
pub use milhouse::{self, List, Vector};
pub use ssz_types::{BitList, BitVector, FixedVector, VariableList, typenum, typenum::Unsigned};
pub use superstruct::superstruct;
```
This PR removes these re-exports and makes it explicit that these types are imported from a non-`consensus/types` crate.

Remove certain dependencies from `eth2`, and feature-gate others which are only used by certain endpoints.
| Removed | Optional | Dev only |
| -------- | -------- | -------- |
| `either` `enr` `libp2p-identity` `multiaddr` | `protoarray` `eth2_keystore` `eip_3076` `zeroize` `reqwest-eventsource` `futures` `futures-util` | `rand` `test_random_derive` |
This is done by adding an `events` feature which enables the events endpoint and its associated dependencies.
The `lighthouse` feature also enables its associated dependencies making them optional.
The networking-adjacent dependencies were removed by just having certain fields use a `String` instead of an explicit network type. This means the user should handle conversion at the call site instead. This is a bit spicy, but I believe `PeerId`, `Enr` and `Multiaddr` are easily converted to and from `String`s so I think it's fine and reduces our dependency space by a lot. The alternative is to feature gate these types behind a `network` feature instead.

Organize and categorize `consensus/types` into modules based on their relation to key consensus structures/concepts.
This is a precursor to a sensible public interface.
While this refactor is very opinionated, I am open to suggestions on module names, or type groupings if my current ones are inappropriate.

Update `reqwest` to 0.12 so we only depend on a single version. This should slightly improve compile times and reduce binary bloat.

Another good candidate for publishing separately from Lighthouse is `sensitive_url` as it's a general utility crate and not related to Ethereum. This PR prepares it to be spun out into its own crate.
I've made the `full` field on `SensitiveUrl` private and instead provided an explicit getter called `.expose_full()`. It's a bit ugly for the diff but I prefer the explicit nature of the getter.
I've also added some extra tests and doc strings along with feature gating `Serialize` and `Deserialize` implementations behind the `serde` feature.

Custody backfill sync has a bug when we request columns from more than one peer per batch. The fix here ensures we wait for all requests to be completed before performing verification and importing the responses.
I've also added an endpoint `lighthouse/custody/backfill` that resets a nodes earliest available data column to the current epoch so that custody backfill can be triggered. This endpoint is needed to rescue any nodes that may have missing columns due to the custody backfill sync bug without requiring a full re-sync.

Currently the `eth2` crate lib file is a large monolith of almost 3000 lines of code. As part of the bosun migration we are trying to increase code readability and modularity in the lighthouse crates initially, which then can be transferred to bosun

Replace all instances of `VariableList::from` and `FixedVector::from` to their `try_from` variants.
While I tried to use proper error handling in most cases, there were certain situations where adding an `expect` for situations where `try_from` can trivially never fail avoided adding a lot of extra complexity.

#7603
#### Custody backfill sync service
Similar in many ways to the current backfill service. There may be ways to unify the two services. The difficulty there is that the current backfill service tightly couples blocks and their associated blobs/data columns. Any attempts to unify the two services should be left to a separate PR in my opinion.
#### `SyncNeworkContext`
`SyncNetworkContext` manages custody sync data columns by range requests separetly from other sync RPC requests. I think this is a nice separation considering that custody backfill is its own service.
#### Data column import logic
The import logic verifies KZG committments and that the data columns block root matches the block root in the nodes store before importing columns
#### New channel to send messages to `SyncManager`
Now external services can communicate with the `SyncManager`. In this PR this channel is used to trigger a custody sync. Alternatively we may be able to use the existing `mpsc` channel that the `SyncNetworkContext` uses to communicate with the `SyncManager`. I will spend some time reviewing this.

#7894
Moves the `Interchange` format from `slashing_protection` and thus removes the dependency on `slashing_protection` from `eth2` which can now just depend on the slimmer `eip_3076` crate.

- [x] Add `beacon_committee_selections` endpoint
- [x] Test beacon committee aggregator and confirmed working
- [x] Add `sync_committee_selections` endpoint
- [x] Test sync committee aggregator and confirmed working
Adds the required boilerplate code for the Gloas (Glamsterdam) hard fork. This allows PRs testing Gloas-candidate features to test fork transition.
This also includes de-duplication of post-Bellatrix readiness notifiers from #6797 (credit to @dapplion)
Adds a new `/lighthouse` API call to the VC which allows the list of beacon nodes to be updated dynamically at runtime.
An entirely new beacon node list is provided to the VC so it effectively adds, removes or reorders nodes to match the new list.
This can then be used in Siren, which will enable a "drag to reorder" system along with adding and removing beacon nodes while the VC is on. This will make it unnecessary to reboot the VC when users want to simply add or remove a BN from the list.
N/A
After the electra fork which includes EIP 6110, the beacon node no longer needs the eth1 bridging mechanism to include new deposits as they are provided by the EL as a `deposit_request`. So after electra + a transition period where the finalized bridge deposits pre-fork are included through the old mechanism, we no longer need the elaborate machinery we had to get deposit contract data from the execution layer.
Since holesky has already forked to electra and completed the transition period, this PR basically checks to see if removing all the eth1 related logic leads to any surprises.
#6970
This allows for us to receive `SingleAttestation` over gossip and process it without converting. There is still a conversion to `Attestation` as a final step in the attestation verification process, but by then the `SingleAttestation` is fully verified.
I've also fully removed the `submitPoolAttestationsV1` endpoint as its been deprecated
I've also pre-emptively deprecated supporting `Attestation` in `submitPoolAttestationsV2` endpoint. See here for more info: https://github.com/ethereum/beacon-APIs/pull/531
I tried to the minimize the diff here by only making the "required" changes. There are some unnecessary complexities with the way we manage the different attestation verification wrapper types. We could probably consolidate this to one wrapper type and refactor this even further. We could leave that to a separate PR if we feel like cleaning things up in the future.
Note that I've also updated the test harness to always submit `SingleAttestation` regardless of fork variant. I don't see a problem in that approach and it allows us to delete more code :)
Closes:

Use `ForkName::latest_stable`, i.e. Electra when decoding blobs from a server that does not provide `version`. This is only a temporary workaround that should be reverted once `checkpointz` is fixed. Having a default fork is potentially incorrect, and glossing over bugs in servers in general is not ideal.
However, even in the case where we update `ForkName::latest_stable` to `Fulu`, this should continue to work, as the blob limit is likely to increase and the `RuntimeVariableList` will just have a slightly higher limit than necessary (which is OK so long as the server isn't buggy enough to violate the correct lower bound: e.g. if the block is an Electra one and the server sends 10 blobs, which exceeds the Electra max (9) but not the Fulu max).
The endpoint `/eth/v1/beacon/states/head/validator_balances` returns an empty data when the data field is `[]`. According to the beacon API spec, it should return the balances of all validators:
Reference: https://ethereum.github.io/beacon-APIs/#/Beacon/postStateValidatorBalances
`If the supplied list is empty (i.e. the body is []) or no body is supplied then balances will be returned for all validators.`
This PR changes so that: `curl -X 'POST' 'http://localhost:5052/eth/v1/beacon/states/head/validator_balances' -d '[]' | jq` returns balances of all validators.
Fix clippy lints for `rustc` 1.87
clippy complains about `BeaconChainError` being too large. I went on a bit of a boxing spree because of this. We may instead want to `Box` some of the `BeaconChainError` variants?

Adds endpoints to add and remove trusted peers from the http api. The added peers are trusted peers so they won't be disconnected for bad scores. We try to maintain a connection to the peer in case they disconnect from us by trying to dial it every heartbeat.
- #6452 (partially)
Remove dependencies on `store` and `lighthouse_network` from `eth2`. This was achieved as follows:
- depend on `enr` and `multiaddr` directly instead of using `lighthouse_network`'s reexports.
- make `lighthouse_network` responsible for converting between API and internal types.
- in two cases, remove complex internal types and use the generic `serde_json::Value` instead - this is not ideal, but should be fine for now, as this affects two internal non-spec endpoints which are meant for debugging, unstable, and subject to change without notice anyway. Inspired by #6679. The alternative is to move all relevant types to `eth2` or `types` instead - what do you think?
