feat: implement storage quota management for uploads

- Added storage quota enforcement for audio and image uploads in the respective routes.
- Introduced reservation system to manage concurrent uploads and prevent quota overages.
- Enhanced comment creation to account for audio and image attachment sizes against user quotas.
- Created new UploadReservation model to track in-flight upload reservations.
- Backfilled existing video assets with size information from R2.
- Added progress component for UI feedback during uploads.
- Updated API responses to include reservation IDs for better quota management.
- Adjusted error handling to return appropriate storage limit exceeded messages.
