fix: uploads and contributions display

- Remove duplicate FamilyUploadSection (PhotoUploadSection already handles this)
- Fix contributions POST: don't require content for timeline/media types
- Save all fields (year, month, day, location, media_filenames) in contributions INSERT
- Add user-uploaded photos from contributions to public photo gallery
- Fix PhotoUploadSection to include title in submission
