feat(freight-api): enrich canonical request log line

Emit the request line as raw JSON on stdout (level/time/logger as fields)
instead of through Nest's console logger, whose prefix made it unparsable.

Collect data points via logCtx at the flow chokepoints: BaseRepository
writes (status changes, creates, deletes), invoice transitions, payment
intent lifecycle + outbound payment-service calls, booking/contract entry
state, review-note reasons, signatures and OTP verify outcomes.
