A quote can now choose which flow runs on acceptance instead of every enabled
quote.accepted flow firing. Migration 147 adds quotes.booking_workflow_id; the
editor shows a "Booking workflow (on acceptance)" dropdown listing the
quote.accepted flows (workflow-engine flag only); emitQuoteEvent passes it as
the new emitWorkflowEvent targetWorkflowId so ONLY the picked flow runs (still
gated on enabled + trigger match → a disabled/None selection runs nothing).
Adds the booking_invoice_only built-in (quote.accepted → prepare invoice →
review gate → send; no event/gallery, no wait), the variant requested for
shoots billed without an online gallery. Disabled stub like the other booking
flows until the prepare_*/send_document cutover.
Tests: targetWorkflowId runs only the selected flow; invoice-only built-in has
no wait/prepare_event.
