Fix Bootstrap version mismatch causing 404 errors on /webjars/** endpoint

[shaykeren]

Problem

Bootstrap version mismatch between Maven and Gradle build systems was causing 404 errors on /webjars/** endpoint:

• Maven (pom.xml) used Bootstrap 5.2.3
• Gradle (build.gradle) used Bootstrap 5.3.2
• Thymeleaf templates hardcoded Bootstrap 5.2.3 references

When deployed with Gradle, templates requested 5.2.3 but only 5.3.2 was available, causing 404s.

Solution

• Updated Maven pom.xml to use Bootstrap 5.3.2 (aligned with Gradle)
• Updated Thymeleaf template to reference Bootstrap 5.3.2 instead of hardcoded 5.2.3

Changes

1. pom.xml: Updated webjars-bootstrap.version from 5.2.3 to 5.3.2
2. layout.html: Updated Bootstrap script reference from 5.2.3 to 5.3.2

Fixes

• Error ID: dfcecee6-5f5e-11f0-a409-0242ac160009
• Trace ID: 8E857253DC0D03C8A8FC8FC5B5563E02
• Affected endpoint: HTTP GET /webjars/**

This minimal fix ensures consistent Bootstrap versions across both build systems and resolves the 404 errors.
