VK's photos.getWallUploadServer only accepts user tokens — community tokens fail with error 27 ('Group authorization failed: method is unavailable with group auth') or error 15. The previous note hinted users could just enable the 'photos' right on a community token, which is wrong: the limitation is hard.
- Restore the accurate fallback warning (community token = photos as links)
- Add an explicit two-path help block: A) user token via Kate Mobile (app_id 2685278) implicit OAuth, with a prefilled authorize URL, B) community token for text-only
