Wires the workflow event bus into the hot paths, AFTER each commit:
- invoiceService.sendInvoice → invoice.sent (idempotent per invoice id, so
overdue re-sends don't double-fire)
- invoiceService.markPaid → invoice.paid, only on the transition into paid
(transaction result captured so the emit runs post-commit, never rolling
back a recorded payment)
- quoteService.recordResponse / adminAcceptQuote / adminDeclineQuote →
quote.accepted / quote.declined via a shared emitQuoteEvent helper that
resolves the customer email for downstream send_email actions
All emits are best-effort and fail closed when the workflows flag is off.
Existing invoice/quote integration tests still green.
