fix: Use secubox-appstore for app installation status in appstore

Instead of trying to parse opkg output directly, use the same
secubox-appstore list --json command that the modules page uses.
This ensures consistent installation detection across both views.

The get_appstore_apps method now:
1. Gets modules list from secubox-appstore (which properly detects installed packages)
2. Merges installation status into catalog apps
3. Returns apps with correct installed/enabled/status fields
