fix: stabilize e2e test suite and auth configuration

- Standardized E2E base URL to 127.0.0.1 to resolve cookie domain 401 errors
- Updated playwright config to strictly exclude security tests from main shards
- Refactored waitForModal helper to prevent strict mode violations on complex modals
- Fixed leak of crowdsec diagnostics tests into standard chromium project
