fix(compose): allow overriding Hub postgres/busybox images on dev path

[fetw882]

Summary

• Dev docker-compose.yml: POSTGRES_IMAGE / BUSYBOX_IMAGE env overrides with unchanged defaults (postgres:16, busybox:1)
• Complements fix(compose): allow overriding Hub postgres/busybox images #493 (published-images) and open fix(compose): allow overriding Hub postgres/caddy images on prod path #494 (prod); this is the local/dev compose path

Helps Mainland / restricted-network developers without shipping regional CDN defaults.

Test plan

• Unset env → same image refs as before
• Set overrides → compose resolves them
• No collision with open installer/Feishu/prod PRs

Summary by CodeRabbit

• Chores
  • Added configuration options for selecting the PostgreSQL and BusyBox container images.
  • Set default images to PostgreSQL 16 and BusyBox 1.

📝 Walkthrough

Walkthrough

The Docker Compose file now allows environment variables to override the PostgreSQL and BusyBox image references. Default image tags remain available when the variables are unset.

Changes

Compose image configuration

Layer / File(s)	Summary
Service image overrides infra/compose/docker-compose.yml	The postgres service uses POSTGRES_IMAGE with a postgres:16 default. The data-init service uses BUSYBOX_IMAGE with a busybox:1 default.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to a3526

The compose change currently causes the PostgreSQL image assertion to fail because the default reference is tag-only instead of digest-qualified. The PR is not merge-ready until the default or its corresponding test contract is aligned.
