fix: align peer_bus signature, bot presence SQL, XML-RPC timeout

- All specialist agents: handle_peer_request(request_type, params, directive_id)
  replaces handle_peer_request(request: dict) so callers pass structured args
- ab_ai_bot: force-write bus_presence.status via SQL so Odoo 18 WebSocket presence
  shows the correct colour immediately (ORM compute does not trigger on last_poll writes)
- odoo_client: wrap XML-RPC executor calls in asyncio.wait_for to enforce timeout
