## Summary
- Replace legacy Dockerfile with native Dagger `container.py` build
- Two-stage pipeline: Elixir+Node builder, Debian slim runtime
- Uses shared helpers (`clone_from_forge`, `oci_labels`)
- Delete old Dockerfile (pipeline auto-discovers container.py)
- Update build-container-image docs and mark service reviewed

## Test plan
- [x] `dagger call build --src=. --container-name=teslamate` succeeds locally
- [ ] CI container build passes
- [ ] Deploy from branch and verify teslamate starts cleanly

### teslamate
`containers/teslamate/Dockerfile` — Two-stage Elixir build with Node.js asset compilation. Uses Debian-based images due to Elixir/OTP dependencies. (Legacy Dockerfile — migrate to `container.py` during review.)
`containers/teslamate/container.py` — Native Dagger build. Two-stage pipeline: Elixir builder with Node.js for asset compilation, Debian slim runtime. Uses Debian-based images (not Alpine) due to Elixir/OTP dependencies. Includes entrypoint script for pg-wait and migrations.
