feat(2.0): Phase 6a — Modell-Install (Download-Jobs + Split + UI)

jobengine portiert (Live-Log + %-Fortschritt aus .incomplete), services/hf.py
(resolve_gguf inkl. Split -of-, Groessen), POST /api/models/install (hf
download als Job + sofortige Registrierung, Split-fest), GET /api/jobs +
cancel. huggingface_hub in requirements. Frontend: Install-Buttons auf
Discover-Karten + Live-Download-Fortschrittsbalken (JobsBar).

Verifiziert: resolve_gguf gegen echte Repos (Qwen3.6-35B-A3B 23GB single,
Qwen3.5-122B-A10B 77GB 3-part split) + Frontend-Build.
