Add AI application assistant: Indeed import + Ollama document generation

- Browser extension (Chromium MV3) injecting a "send to tracker" button next
  to the Indeed job description; scrapes job info and posts it to a new
  /api/indeed-import endpoint (CORS-enabled), configurable tracker URL via popup.
- New "Entwurf" status. Imports create a draft and trigger background AI
  generation of tailored Anschreiben + Lebenslauf (PDF attachments) via the
  Ollama Cloud API, grounded strictly in user-provided base documents.
- Vorlagen page to manage base documents; attachments UI, generation status
  polling, regenerate and download routes on the application page.
- Schema: ort/stellenbeschreibung/quelle_url/generierung_* columns, plus
  basis_dokumente and anhaenge tables (with migrations).
- Config via .env (OLLAMA_API_KEY/OLLAMA_MODEL/OLLAMA_HOST); dependency-free
  .env loader. Dockerfile copies lib/, .dockerignore added.
