Approve SIL Transaction

Approve a held transaction and apply the balance impact to SIL.

Cmd: SITApproveTransactionCommand

What the handler does

1. Re-loads the transaction and validates it is still Pending / PendingApproval.
2. Re-validates the account is not now Frozen, Closed, or Dormant.
3. Recomputes leg impact from persisted SITTransactionEntry rows.
4. Re-checks sufficient funds for debit scenarios.
5. Applies balances and backfills RunningBalance on the entries.
6. Sets Status = Posted, ApprovalStatus = Approved.
7. Inserts the SITSyncQueue row so replay to core can begin.
