Рефакторинг: KISS принципы, разбиение god-классов, реорганизация

- Создан RatConfig.java с централизованными константами
- MuteServiceImpl: 261→170 строк (Strategy pattern)
- MessagingServiceImpl: 219→124 строк (3 отдельных сервиса)
- ServiceFactory для создания сервисов
- Реорганизованы директории: utils/, commands/moderation/, commands/admin/
- Все директории теперь ≤6 файлов
