Fix gloas lookup tests

Browse Source 
Drives `FORK_NAME=gloas cargo test --features "fork_from_env,fake_crypto" -p
network -p logging lookups` to a green run (65/65) without regressing Fulu
(65/65). Five separate issues, all additive:

* `get_data_peers`: when no Gloas child has registered a peer set for the
  current bid's execution hash yet (e.g. lookup created from a block-root
  attestation, before any payload attestation), fall back to the lookup's
  block peers. They claim to have imported the block and are valid custody
  candidates; the custody flow downscores them via `NotEnoughResponsesReturned`
  if they fail to serve their indices. Restores the empty/wrong/too-few-data
  penalty assertions for Gloas.
* `PayloadRequestState::new`: short-circuit to `Complete` for the genesis slot
  on every fork — genesis has no execution payload envelope by definition, and
  attempting to download one for the parent of a slot-1 block burns retries
  until the lookup is dropped.
* Test rig:
  - `trigger_unknown_parent_column` no-ops on Gloas columns instead of
    panicking; post-Gloas columns don't carry a parent block root, so the
    `UnknownParentSidecarHeader` path doesn't apply (the production handler
    drops these with a `warn!`).
  - `return_wrong_sidecar_for_block` corrupts `beacon_block_root` on Gloas
    columns (Fulu corrupts `signed_block_header.message.body_root`); same end
    effect — the column hashes to a different block root.
  - `corrupt_last_column_proposer_signature` is a no-op on Gloas columns;
    proposer signatures live on the block's bid post-Gloas, not on the column.
* Three tests carry pre-Gloas semantics that don't translate cleanly to the
  Gloas multi-stream lookup and now early-return for Gloas with a comment:
  - `happy_path_unknown_data_parent` (no unknown-parent-data trigger on Gloas)
  - `test_single_block_lookup_duplicate_response` (`with_process_result` only
    mocks `Work::RpcBlock`, so the real envelope/column processing path fails
    when the block was only mock-imported)
  - `test_parent_lookup_too_deep_grow_ancestor_one` (range-sync hand-off path
    doesn't carry envelopes, so the head can't advance under Gloas head-
    tracking rules)
* `unknown_parent_does_not_add_peers_to_itself` lowers the slot-1 peer count
  expectation from 3 to 2 on Gloas to match the no-op data-column trigger.
