fix(qa): health check, admin notice, docs, logo, Coolify port

- WP Advanced health_check uses aiohttp to /wp-json/ directly
- SEO Bridge admin notice only on Plugins page
- SEO Bridge README.md consolidated, changelog complete
- OpenPanel Self-Hosted README.md created
- Dashboard sidebar uses actual logo.svg
- docker-compose: expose instead of ports for Coolify
- README: version badge, wordpress_advanced endpoint, env var table
- Docs: SSE references fixed to streamable-http
