feat(bots): refine event binding editor UI and i18n

- Move conditions toggle between event select and arrow; drop "IF" label
- Remove "all events" (*) option from event select
- Add i18n labels for concrete event names (zh/en/ja) via bots.eventNames
- Narrow fallback event set to message.received for adapters without
  declared supported_events (legacy adapters only emit message.received)
