Manual generation, LLM notes with company address, and static attachments

- Static extra attachments: upload files (e.g. Zeugnisse) once on the Vorlagen
  page; they are attached to every generated application and listed under
  "Anlagen" in the cover letter (via multer upload + basis_anhaenge table).
- Import no longer auto-generates: an imported job is saved as a draft
  ("nicht_gestartet"); generation is triggered manually on the application page.
- Per-application "LLM-Notizen" field: free text (company address, contact
  person, extra context) that is fed to the model at generation time. Saving the
  notes and (re)generating happens in one action.
- Cover letter recipient block is now a structured empfaenger (firma, address,
  city, contact person) the model fills from the job + notes; the salutation
  adapts to a named contact. Falls back to the imported company + city.
- Raise default OLLAMA_TIMEOUT_MS to 300s for slower cloud models.
