The "Allowed File Types" admin setting was stored in the database but
never actually read during upload validation. Both frontend and backend
used hardcoded MIME type lists, causing video uploads (e.g. MP4) to be
rejected even when explicitly added to the setting.
Changes:
- Add getAllowedMimeTypes() to uploadSettings service that reads the
general_allowed_file_types DB setting and converts extensions to MIME types
- Backend admin upload route now resolves allowed types from settings
before multer processes files (via resolveAllowedTypes middleware)
- Backend gallery upload route uses dynamic allowed types from settings
- Expose allowed_file_types in public settings API for gallery clients
- Frontend PhotoUpload and UserPhotoUpload components now derive allowed
MIME types from settings instead of hardcoded image-only lists
- Add shared fileTypes.ts utility for extension-to-MIME conversion
