fix(e2e): resolve E2E test failures

- Update fixture mock user IDs to match test expectations (client-1, client-2)
- Fix admin-reports strict mode violation: replace .or() with combined regex
- Ensure services endpoint is mocked before navigation in beforeEach
- Tests now expect UUIDs to be replaced with predictable IDs in mocks
