Cleanup: odstrani duplikat upload-nextcloud endpoint

Endpoint /api/jobs/{id}/upload-nextcloud je že obstajal (commit dbb8ab3)
in deluje. Moja nova varianta je bila duplikat — odstranjena.

Aktivni endpoint: line 1593 (upload_nextcloud), uporablja
_nextcloud_upload() in _nextcloud_configured() helper-je.

Zdaj imamo:
- _safe_filename_for_nextcloud() helper (ostane, lahko pride prav)
- Frontend gumb '☁ Nextcloud' z 4 stanji (default/uploading/uploaded/failed)
- 14 reelov že uspešno uploadanih v /folxspeed/REELS/FOLX SLOVENIJA/
