fix: add TLS support for PostgreSQL connections (#363) (#427)

All PostgreSQL connection sites hardcoded NoTls, preventing connections
to managed providers that require TLS (AWS RDS, Neon, Supabase, etc.).

- Add tokio-postgres-rustls with rustls + system root certificates
- Add SslMode enum (disable/prefer/require) via DATABASE_SSLMODE env var
- Replace NoTls at all 4 production call sites with TLS-aware pool creation
- Add SslMode::from_env() helper for lightweight CLI tools
- Log native cert loading errors and warn on empty root store

Default mode is Prefer (attempts TLS, matching most managed providers).
