Fix page crashing issues

- Fix nullable parameter deprecation warning in setResponse method
- Remove non-existent HomepageUserWatchStats trait that was causing fatal errors
- Revert formatJellyStatDuration back to formatDuration in JellyStat component
- Ensure proper trait loading and function references

These changes resolve the primary causes of page crashes and PHP warnings.
