Commit Message

[coordinator] Fix VC manager in-flight transaction tracking

#### Type of change

- Bug fix
- Test update

#### Description

- Return the transactions to `txBeingValidated` when forwarding their results fails, so that
  `recoverPendingTransactions` can re-queue them instead of dropping them. The signature verifier
  manager already guards this invariant, the VC manager did not.
- Move the map insertion into a new `addTxsBeingValidated`, mirroring the verifier manager, so the
  key is computed in one place.
- Key `validatorCommitter.txBeingValidated` by `servicepb.Height` rather than `TxRef.TxId`, again
  mirroring the verifier manager. The height is the transaction's own identity within the block, so
  matching a status back to its node no longer depends on transaction IDs being unique among the
  transactions currently in flight.

#### Additional details (Optional)

The failed-forward re-add is currently reachable only while the manager itself is tearing down,
because both output writes are bound to the manager's context rather than the stream's. It is
guarded here so the invariant holds regardless of how those contexts are wired later.

`TestValidatorCommitterAddAndRecoverPendingTxs` covers the add/recover round trip that the guard
relies on.
