fix: handle 400 errors from Telegram callback interactions

- Remove redundant editMessageText in CALLBACK_REPLY (text unchanged)
- Wrap answerCallbackQuery in try/except (non-critical)
- Wrap each update in its own try/except to ensure last_update_id
  always advances, preventing infinite retry loops
