LR-LIB-BYDATE + LR-META-COPYRIGHT-DEFAULT: By Date day tree, default copyright/creator on import

- By Date: year → month → day rows with counts and disclosure triangles; a row filters by
  that date prefix (catalog date_groups now carries days).
- Settings → Import → Metadata: copyright and creator given to imported photos that don't
  carry their own (library.preferences {import: {copyright, creator}}), saved with the library.
