Initial setup: Web hosting default container with auto-landing page

- Added Dockerfile with Apache base image
- Created beautiful web hosting landing page (index.html)
- Added startup script to check for content and copy default page
- Set up Gitea workflow for automatic builds
- Updated README with comprehensive documentation

The container automatically provides a professional landing page when the web directory is empty, focusing on web hosting features and guiding users to configure their site through the Web Hosting Panel.
