fix(e2e): use Playwright web installer + session-based token creation for Matomo 5.3

- make Playwright a runtime dependency (installer requires it)
- record-and-replay Matomo web installer flow (more stable than container bootstrap)
- replace removed UsersManager.getTokenAuth with cookie-session login + createAppSpecificTokenAuth
- make HttpClient return (status, body) for HTTPError responses
- set deterministic container names in docker-compose and pass MATOMO_CONTAINER_NAME
