Fix KeyError for userProfileId and add reload support

- Fix KeyError when userProfileId is missing from summary after HA updates
- Check if userProfileId exists before accessing it in 3 locations
- Remove duplicate get_gear() call, reuse data from first fetch
- Add async_reload_entry() function for reload without restart
- Update README with reload instructions
- Improves integration reliability and user experience
