refactor: remove bootstrap wrappers and split into config/service/installers

- Replace bootstrap wrapper with config-driven service orchestration
- Introduce Config dataclass for centralized env/CLI validation
- Add MatomoApi service for session login + app token creation
- Move Playwright installer into installers/web and drop old install package
- Refactor HttpClient to unify HTTP handling and debug to stderr
- Make E2E tests use sys.executable instead of hardcoded python3
