fix(character-dictionary): normalize fallback titles and wire close button

- Trim blank fallback titles in toAniListMediaCandidate; fall back to
  \"AniList <id>\" when all title fields and the fallback string are empty
- Add fetch unit test covering the trimmed-fallback path
- Extract wireDomEvents from createCharacterDictionaryModal so event
  listeners are bound explicitly after construction
- Call wireDomEvents in renderer init alongside other modal wiring
- Extend modal test to cover close-button click dismissing the modal
