build(images): pin multigres to sha-bb174f9, pgctld to sha-9b51b0f

Upstream includes a startup deadlock fix (HTTP server now starts
before run hooks), a connection recycle bugfix (RESET ROLE/SESSION
AUTHORIZATION before RESET ALL), and POSTGRES_DB env var support.

- Update multigres image sha-f02e476 → sha-bb174f9
- Update pgctld image sha-f02e476 → sha-9b51b0f
- multiadmin-web unchanged at sha-b505c90

All upstream changes are transparent to the operator: CLI flags
take precedence over new env vars, and internal fixes require no
operator-side modifications.
