feat(fusion_accounting_ai): 5 new bank-rec AI tools wrapping engine

Adds fusion_suggest_matches, fusion_accept_suggestion,
fusion_reconcile_bank_line, fusion_unreconcile, and
fusion_get_pending_suggestions. All route through the BankRecAdapter
(or direct engine for ones the adapter doesn't expose), giving the AI
chat the same reconciliation surface a human operator gets in the OWL UI.

Made-with: Cursor
