chore: update OpenAPI documentation paths and enhance references

- Changed input path for documentation generation from './api.json' to '../../public/openapi.json'.
- Updated multiple generated documentation files to reference the new OpenAPI document path.
- Added new documentation files for 'Environment', 'Gitea', 'Organization', 'Preview Deployment', 'Rollback', 'Schedule', 'Swarm', and 'Volume Backups'.
- Enhanced existing documentation with additional endpoints and improved structure for clarity.
