Upload Promo Video

POST 
/api/share/promo-video/upload

Upload a promo-video file server-side and return its b2_key.

Dedicated to Share & Earn so any authenticated sharer can upload (the shared /api/upload/attachment route is gated by settings:view). Stores the file in the public Backblaze bucket under uploads/{tenant}/promo_videos/ via UploadService and returns the bucket-relative key for /set-source.
