apollo_storage: add helper to build declared class component hashes for a block

apollo_committer: test new edge bottom in witnesses (#14388)

apollo_committer: reduce tests boilerplate (#14425)

apollo_propeller: added unit test infrastructure for testing behaviour (#12273)

Add unit-test infrastructure to exercise the apollo_propeller libp2p Behaviour in
isolation, driving it directly through its NetworkBehaviour interface without spinning
up a real swarm.

• Add behaviour_test.rs (gated behind #[cfg(test)] from lib.rs) with two harnesses:

  • TestNode: wraps a Behaviour plus its PeerId and drives it via on_swarm_event,
    on_connection_handler_event, and poll.
  • TestEnvironment: holds a BTreeMap of nodes keyed by PeerId, with helpers to build
    a full mesh and register a single equal-weight committee over all nodes.

• simulate_* helpers (simulate_connect_to, simulate_receive_unit, simulate_connect_all)
  inject swarm/handler events; expect_* helpers poll for and assert on emitted ToSwarm
  events under a timeout; next_with_timeout polls the behaviour with a timeout.

• Named the event-injection helpers with a simulate_ prefix so call sites make clear they
  simulate swarm interactions rather than perform real ones, and to distinguish them from the
  expect_* assertion helpers (per review feedback).

• Named the polling helper next_with_timeout rather than next_timeout, which reads as "the
  next timeout" instead of "the next event, with a timeout" (per review feedback).

PR Summary

Low Risk
Read-only storage aggregation with a focused test; no write-path or auth changes.

Overview
Adds get_declared_class_hash_to_component_hashes in apollo_storage so callers can build the per-block declared_class_hash_to_component_hashes map expected by the OS block input from stored state diffs and Sierra classes.

For a given block it walks class_hash_to_compiled_class_hash in the state diff, keeps only Cairo 1 classes whose first declaration block matches that block (via get_class_definition_block_number), loads each Sierra class, and maps class hash → ContractClassComponentHashes from get_component_hashes(). Entries that only migrate an existing class’s compiled class hash are skipped.

A unit test covers fresh declaration vs migration across two blocks. ContractClassComponentHashes gains Eq/PartialEq in starknet_api for those assertions.
