- Changed AdminController to use simple echo/exit instead of TemplateResponse
- Eliminates TemplateResponse complexity
- Direct HTML output for debugging
- Simplified routes.php to single admin route
- Removed test route (no longer needed)
- Simple GET only route
- Simplified Application.php
- Removed resource loading
- Minimal bootstrap
If this shows 'Controller is working' page, routing is confirmed working.
If it still redirects to dashboard, it's a Nextcloud routing issue.
This is a minimal test version to confirm routing works before building full UI.
