chore(release): v1.28.47 — job queue engine update (pg-boss 12.26)

Bumps pg-boss 12.20 → 12.26 (schema-drift detection, self-healing background
index builds, correctness fixes). Some of those fixes surface errors earlier
versions silently swallowed. Verified safe: the app attaches an error listener
to the boss instance (reminder-worker.ts) and uses none of the direct calls the
change affects (insert/fetch/deleteQueue) — only send/work/start/stop/schedule/
getJobById, and the one getJobById is already wrapped in try/catch. The full
integration suite (101 files, 497 tests) exercising the queue against real
Postgres passes unchanged under 12.26. No config change.
