All API routes were moved under /api prefix as part of the unified
deployment architecture. Updated test files to reflect this change:
- basics.rs: Update root and auth/providers routes
- health.rs: Update health endpoint routes
- oauth.rs: Update all OAuth and auth callback routes, plus redirect locations
- sessions.rs: Update profile and logout routes
This fixes 9 failing tests that were expecting routes without the /api prefix.
- Add retry configuration for flaky tests (2 retries for default, 3 for
OAuth)
- Configure test groups with proper concurrency limits (serial: 1,
integration: 4)
- Add tower-http tracing layer with custom span formatting for HTTP
requests
- Simplify database pool handling by removing unnecessary Arc wrapper
- Improve test context setup with better logging and error handling
- Refactor user creation parameters for better clarity and consistency
- Add debug logging for OAuth cookie handling
