feat: wire context broker files category to FileBrowser, fix media state check

- sanitizeFiles() now fetches real data from FileBrowser (usage, folders, recent files)
- Fixed media state check to include 'running' and 'stopped' states, not just 'installed'
- Removed unused bottomPosition variable in CloudFolder.vue
