Add AI photo import via Ollama Vision

Users can upload a photo of a nail polish bottle; a background queue
job sends it to Ollama (llama3.2-vision at 192.168.30.172:11434),
extracts name, number and manufacturer, then creates the nail polish
and adds it to the user's collection automatically.

- ProcessNailPolishImage job (180s timeout, 2 tries)
- NailPolishImport model + migration (status tracking)
- AiSetting model + migration (Ollama URL + model, admin-configurable)
- NailPolishImportController: upload, status page (auto-refresh every 5s)
- Admin\AiSettingController: configure Ollama connection
- Views: drag-drop upload form, live status page, import history
- Navbar: "Foto importieren" link for all users
- Admin dropdown: "KI-Einstellungen"
- neonail-worker.conf: Supervisor config for the queue worker
