feat: add panelVersion to ServiceEvent and update event handling

- Introduced `panelVersion` property in `IServiceEvent` interface.
- Updated `onPanelStarted` method to utilize `panelVersion` from the event data instead of the package version.
- Adjusted `onApplicationBootstrap` to emit `panelVersion` when the panel starts.
