refactor: extract RoutingRulesEditor component, revert log levels to debug

- Extract ~250 lines of inline routing rules UI from BotForm into
  a dedicated RoutingRulesEditor component
- Revert stage interrupt and event prevented-default log levels
  from warning back to debug (these are normal flow, not errors)
- Remove message content from log lines to avoid leaking user data
