fix: include web assets in Docker image for proper CSS/JS serving

Added web static files (CSS, JS, templates) to Docker image build:
- Copy web templates and static assets to container
- Create web directories with proper permissions
- Ensures enhanced web interface displays correctly in Docker

Resolves styling issues when running the web interface in containers
where CSS and JavaScript files were missing from the image.
