chore(SpringBoot): Upgrade to 3.4.13

[hirokiterashima]

Description

Upgrades the application from Spring Boot 3.3.13 to Spring Boot 3.4.13 (and underlying dependencies including Spring Framework 6.2 and Hibernate 6.6), aligns JPA entity ID generation strategies, cleans up deprecated configurations, and adds standard Java 14 @Serial annotations.

Summary of Changes

1. Spring Boot 3.4 Upgrade

• Bumped <parent> version in pom.xml from 3.3.13 to 3.4.13.

2. JPA & Hibernate Configuration

• Entity ID Generation Strategy: Changed @GeneratedValue(strategy = GenerationType.AUTO) to GenerationType.IDENTITY in Chat.java and ChatMessage.java to align with the MySQL auto_increment schema and all other domain entities.
• Deprecated ID Generator Mapping: Removed obsolete spring.jpa.hibernate.use-new-id-generator-mappings setting from HibernateConfig.java and sample property files (Hibernate 6 no longer supports disabling new generator mappings).

3. Dependency Cleanup

• Replaced WordUtils.wrap() in ProjectServiceImpl.java with a native pure-Java wrapText(String, int) helper method, eliminating the need to add org.apache.commons:commons-text as an explicit dependency.

4. Code Modernization

• Added @Serial annotation to serialVersionUID fields across domain, parameter, and exception classes.

5. New tests

• Added unit tests for chat/chatbot domain, project text wrapping, and controller utilities

Verification

• Compilation: mvn clean test-compile compiles cleanly with zero errors.
• Unit & Integration Tests: Executed mvn test — all 585 tests passed with 0 failures and 0 errors (1 skipped, matching baseline).
• Packaging: Verified WAR packaging with mvn package -DskipTests; wise.war generated and repackaged cleanly via Spring Boot 3.4.13 loader tools.
• Application: Restart wise-api Docker container and make sure that WISE works as before. Test thoroughly (save student data, author new units, etc)
