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

Issue Description

The application is experiencing a "Webjars Bootstrap Resource Not Found Error" when trying to access Bootstrap resources through the webjar path.

Root Cause

1. Missing proper Webjars resource configuration in Spring Boot
2. CSS profile not activated during build process

Solution

1. Added proper Webjars configuration in application.properties:

   spring.mvc.static-path-pattern=/webjars/**
   spring.web.resources.static-locations=classpath:/META-INF/resources/webjars/
   spring.web.resources.chain.strategy.content.enabled=true
   spring.web.resources.chain.strategy.content.paths=/webjars/**

2. CSS profile must be activated during build:

   ./mvnw clean package -P css

Related PR

See PR #440 for the implementation.

Validation Steps

1. Build with CSS profile: ./mvnw clean package -P css
2. Verify contents of target/webjars directory
3. Start application and verify Bootstrap resources are accessible through webjar paths
