Fix: Rename app folder to match app ID

- Renamed analytics-hub/ → analyticshub/
- App ID in info.xml is 'analyticshub' (no hyphen)
- Nextcloud requires folder name to match app ID exactly
- Fixes 'Could not download app analyticshub' error during installation

Installation:
- Upload analyticshub/ folder to /var/www/nextcloud/apps/
- Folder name must match app ID in info.xml

analyticshub/lib/AppInfo.php
