## What changed

- Replaced hard error with inline app installation offer for missing Subcontracting or IT Subcontracting Migration apps
- Uses ExtensionManagement.InstallMarketplaceExtension pattern, triggering session reload to re-run the disable process
- Pre-Check action also provides install option instead of dead-ending
- Method signature unchanged to maintain compatibility with existing cross-app calls
- Removed unused error labels for app-not-installed scenarios
- Behaviour changes for users or extensions.
