feat: Profile-System für unterschiedliche Use-Cases (Sitzungsprotokoll, später Arzt-Diktat etc.)

Mac-Worker:
- profiles/meeting.yaml — extrahiert die bisherigen Prompts + DOCX-Layout
- core/profiles.py — YAML-Loader mit Cache und Fallback
- ollama_client.summarize/make_protocol nehmen profile_name
- docx_export: generischer Renderer aus profile.docx (meta + sections mit
  Typ text/list/tasks/transcript)
- /api/profiles listet verfügbare Profile
- pyyaml als Dependency

LXC:
- Job.profile + User.default_profile (Migration: ALTER TABLE)
- /api/profiles proxy mit 60s-Cache und Fallback
- Upload-Form akzeptiert profile (Server-Default: user.default_profile)
- Pipeline gibt Profile bei summarize/protocol/docx an Mac weiter
- PATCH /api/auth/me — User kann Standard-Profil ändern

Frontend:
- Profile-Dropdown im Upload (nur sichtbar wenn ≥2 Profile)
- Settings-Karte "Mein Standard-Profil" (nur wenn ≥2 Profile)
- Job-Zeile zeigt grünes Profile-Tag (nur wenn relevant)

Neue Profile = neue YAML-Datei in mac-worker/profiles/ — kein Code-Deploy
nötig, der Mac-Worker liest sie beim Start ein.
