fix: handle NoSuchMethodError in SerialSettingsPage

- Add defensive error handling for EclipseUtil.getSelectedIDFProjectInExplorer()
- Implement fallback to getSelectedProjectInExplorer() with IDF nature check
- Prevent terminal opening crash when no project is selected
- Gracefully handle bundle version conflicts in OSGi runtime
