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

This PR addresses the Webjars Bootstrap Resource Not Found Error by:

1. Adding proper Webjars resource configuration in application.properties:

   • Configured static path pattern for webjars
   • Set up proper resource chain strategy
   • Added static locations configuration

2. Important Note:
   The CSS profile must be activated during build using:

   ./mvnw clean package -P css

   This ensures Bootstrap resources are properly unpacked to the target/webjars directory.

The changes ensure that Bootstrap resources are properly served through the webjar path.
