0xMushow 9065e4a56e fix(beacon_node): add pruning of observed_column_sidecars (#8531) ...

None


  I noticed that `observed_column_sidecars` is missing its prune call in the finalization handler, which results in a memory leak on long-running nodes (very slow (**7MB/day**)) :

13dfa9200f/beacon_node/beacon_chain/src/canonical_head.rs (L940-L959)

Both caches use the same generic type `ObservedDataSidecars<T>:`
22ec4b3271/beacon_node/beacon_chain/src/beacon_chain.rs (L413-L416)

The type's documentation explicitly requires manual pruning:

>  "*The cache supports pruning based upon the finalized epoch. It does not automatically prune, you must call Self::prune manually.*"


b4704eab4a/beacon_node/beacon_chain/src/observed_data_sidecars.rs (L66-L74)

Currently:
- `observed_blob_sidecars` => pruned
- `observed_column_sidecars` => **NOT** pruned

Without pruning, the underlying HashMap accumulates entries indefinitely, causing continuous memory growth until the node restarts.
