fix(M-AI-02-GATE): restore physical column names, composite UNIQUE, lifecycle spec, migrate deploy

Section 2: @map("errorMessage") + @map("completedAt") decouple logical from physical names.
  Forward-fix migration reverts physical columns to original names.
Section 3: jobType VARCHAR(64) → VARCHAR(32) restored.
Section 4: lifecycleStatus mapping restored to spec (pending→queued, processing→running,
  completed→succeeded, failed→failed). Enum: created|queued|running|retrying|succeeded|
  failed|cancel_requested|cancelled.
Section 5: idempotencyKey UNIQUE changed from single-column to composite
  (userId, jobType, idempotencyKey). MySQL allows multiple NULLs.
Section 6: triggerType backfill now documents evidence basis per record.
Section 7: CI deploy.yml uses prisma migrate deploy (not db push).
  Migration baseline established (28 rows in _prisma_migrations).

prisma migrate diff: No difference detected.
332 tests pass.
