test(settings): add AddKeyForm + OrgTokensTab + SecretRow + SecretsTab coverage

Cherry-picked from test/settings-tab-coverage (PRs #708/#726).
- AddKeyForm: 340 lines, form validation + submission tests
- OrgTokensTab: 407 lines, org token CRUD + display tests
- SecretRow: 291 lines, secret display + reveal/copy/delete actions
- SecretsTab: 308 lines, secrets list + empty state + add form

Makes #704 a true superset of all settings test coverage.
