- Change image from timescaledb-ha:pg16-ts2.15-oss to pg16-ts2.15
(OSS edition lacks compression, retention, continuous aggregates)
- Add postgresql-client to Dockerfile for psql binary
- Rewrite run_migrations.py to use psql instead of psycopg2
(psql runs each statement independently; psycopg2 wraps the
entire file in one transaction so one error rolls back everything)
- Add schema verification: exits 1 if critical tables missing,
preventing services from starting with broken schema
