Add DreamDict integrations: translate, hangman clues, and Portuguese WOTD

- Replace LibreTranslate-based !translate with DreamDict cross-language
  lookup (en/fr/pt-PT) with auto-detect and 5-per-lang cap
- Add multilingual hangman mode (!hangman <lang> [--clue <lang>]) using
  DreamDict RandomWord/Translate with retry logic and race-safe placeholder
- Rewrite WOTD to pick pt-PT words with Portuguese definitions and
  en/fr translations, add !wotd force for moderators
- Move DreamDict client init earlier in main.go for broader availability
- Wire dictClient into LookupPlugin, HangmanPlugin, and WOTDPlugin
