Birthday & anniversary photo collections

- profiles get an optional birthday (MM-DD); photos of that person taken on the
  date are also copied into Birthdays/<person>/<year>/
- app-wide anniversaries (label + MM-DD); any photo taken on the date is copied
  into Anniversaries/<label>/<year>/ (including faceless photos and videos)
- copy (not move) so normal person/date sorting is preserved
- CaptureDate gains day; new collection path builder; scanner skips the new folders
- UI: birthday input in profile create/edit + new Anniversaries manager
