feat(ci): refactor Gitea workflow to separate k6 health baseline tests

- Introduced a new job `k6-health-baseline` in the Gitea CI workflow to run health checks independently from Playwright tests, enhancing clarity and organization.
- Updated documentation to reflect the changes in the CI pipeline, specifying the execution order and purpose of each job.
- Adjusted environment variables and health check logic for both development and production modes, ensuring accurate testing conditions.
