Fix User Watch Stats save button issue by using global config keys for permissions

- Updated userWatchStatsHomepagePermissions() to check global media server config keys (plexURL/plexToken, embyURL/embyToken, jellyfinURL/jellyfinToken) based on selected server
- This matches the pattern used by EmbyLiveTVTracker and ensures Organizr recognizes the required fields for enabling the save button
- Plugin still uses dedicated URL/token fields for functionality, but permissions now check global keys
- Resolves issue where save button wasn't appearing for User Watch Stats plugin
