fix(e2e): remove duplicate links test files and fix wizard navigation test

- Delete e2e/links.spec.ts and e2e/links-advanced.spec.ts (duplicates of integrations*.spec.ts)
- Add label creation to wizard navigation test before selecting from dropdown
- Fixes CI failure where dropdown had no options (index 1 not found)
