Add ticket code search across client-side and server-side search

- Client-side: searchFilterCards now matches card ticket codes
  (e.g. typing "PROJ-42" in view header search finds the card)
- Server-side: board search (both searchBoardsForUser and
  searchBoardsForUserInTeam) now includes card_prefix in OR
  conditions, so searching "PROJ" finds boards with that prefix
- New BoardSearchFieldCardPrefix for dedicated prefix search
- Updated search placeholder to hint at ticket code search
