feat: add click_ad action for ad element interaction

- Add new click_ad action that can find and click ad elements automatically
- Support both auto-discovery of common ad selectors and explicit selector input
- Add screenshot capture before and after ad clicks
- Update frontend UI to include click_ad in action lists
- Add comprehensive test coverage for all ad click scenarios
- Update gitignore to exclude .blackboxcli/
