"""Integration test for multi-user Astrolabe background sync enablement.

This test verifies that multiple users can independently:
1. Log in to Nextcloud
2. Generate an app password in Security settings
3. Enter the app password in Astrolabe personal settings
4. Enable background sync for the mcp-multi-user-basic service
5. Verify app password is stored in the database

Tests the complete app password provisioning flow:
user login → Security settings → app password generation → Astrolabe settings →
app password entry → background sync activation → database verification.
