n.siegfried a33b777aca Add Python/FastAPI + PostgreSQL backend (Phase 1)
- server/: FastAPI app with SQLAlchemy models for sops, work_packages, comments
- Endpoints for SOP/WP upsert+list+get+delete and comment create+list;
  /api/feedback kept as an alias so the existing client keeps working
- Portable across engines (PostgreSQL prod, SQLite dev fallback)
- requirements.txt, .env.example, and server/README.md (Postgres + systemd)
- NGINX now proxies /api/ to the API (replaces the Power Automate hop;
  comments persist to SQL)
- Rewrite DEPLOYMENT.md for the API + database architecture
- Add .gitignore for venv/.env/sqlite

Phase 2 (wire the client apps to the API) is next.

"""ORM models for the Work Package Suite.
Three tables:
- sops one row per project SOP (the configuration baseline)
- work_packages one row per IWP, optionally linked to a SOP
- comments feedback / review comments from any page
The full client document for a SOP or WP is kept verbatim in a JSON `data`
column, with the most-queried fields promoted to real columns for listing and
filtering. IDs are short strings (client- or server-generated) so the browser
can upsert without round-tripping a sequence.
