fix(i18n): translate remaining German hardcoded strings in PhotoUpload

Replace 6 hardcoded German strings in PhotoUpload.tsx with t() calls:
- 'Tag verknüpfen' → t('photos.linkDay')
- 'Kein Tag' / 'Tag N' → t('photos.noDay') / t('photos.dayLabel')
- '{N} Foto(s) ausgewählt' → t('photos.photoSelected/photosSelected')
- 'bis zu 30 Fotos' hint → t('photos.fileTypeHint')
- 'Wird hochgeladen...' → t('common.uploading')

Add all 6 new keys to all 14 language files and update test
assertions from German strings to English equivalents.
