Fix Webjars Bootstrap Resource Not Found 404-created-by-agentic

[shaykeren]

Issue: Bootstrap resources served through Webjars are returning 404 Not Found errors.

Root Cause:
The application is missing proper WebMVC configuration for handling Webjars resources. This prevents Spring from correctly serving static resources from the Webjars dependencies.

Solution:

1. Added WebMvcConfigurer implementation to properly handle Webjars resources
2. Configured resource chain optimization for better performance
3. Ensured proper classpath resource locations for Webjars

Additional Monitoring:
To prevent similar issues in the future, we should:

1. Add monitoring for static resource loading
2. Set up alerts for 404 errors on static resources
3. Consider implementing health checks for critical UI dependencies
