fix: E2E select dropdown reliability and stale eslint-disable directives

- Fix Radix Select interaction in proxy host E2E helper: scroll trigger
  into view and wait for option visibility before clicking (fixes flaky
  access-control.spec.ts timeout)
- Apply same fix to certificate selector for consistency
- Remove stale eslint-disable directives from pre-existing test files
  (now covered by test-wide eslint config override)
