Unit Tests / test (push) Successful in 10s
## Summary - Containerize the Django app with Docker and docker-compose (dev + production) - Refactor settings into `dev` / `beta` / `prod` environments driven by environment variables - Connect to PostgreSQL via `DATABASE_URL` or `DB_*` vars - Migrate package management from pip to uv (`pyproject.toml`, `uv.lock`) - Split Gitea workflows: PRs run unit tests only; pushes to `master` run tests, Docker validation, and deploy - Update deploy script to rsync code, preserve server `.env`, validate config, and run Docker compose Closes #4 ## Test plan - [x] `uv run python manage.py test` passes locally (10/10) - [x] `DJANGO_ENV=beta` and `DJANGO_ENV=prod` load with correct logging levels - [x] `scripts/validate-env.sh` rejects missing production variables - [ ] `docker compose up --build` starts app + Postgres locally - [ ] Containerized unit tests pass in CI Docker job - [ ] Server `.env` created from `.env.prod.example` before first production deploy - [ ] CI workflow runs on this PR (tests only, no deploy) Reviewed-on: #6
