Update Java version from 1.8 to 11 in pom.xml

Summary

Updated the Maven <java.version> property from 1.8 to 11 in pom.xml. This is Step 1 from Group 1 of the Java 11 migration plan for the Spring Boot banking application.

Changes:

• Updated <java.version> property in pom.xml from 1.8 to 11

Verification performed:

• ✅ mvn compile - BUILD SUCCESS
• ✅ mvn test - 1 test passed, BUILD SUCCESS

Review & Testing Checklist for Human

• Verify CI/CD pipelines are configured to use Java 11 (GitHub Actions, Jenkins, etc.)
• Check if Dockerfile or deployment configurations need Java version updates
• Test the application end-to-end in a dev/staging environment (not just unit tests)
• Verify deployment environments (staging/production) support Java 11 runtime
• Confirm this aligns with the overall Java 11 migration plan - are there other dependencies or configurations that should be updated together?

Notes

This is a straightforward property change that only updates the Maven compilation target. While local compilation and unit tests pass, this change will require the actual runtime environment to support Java 11. Other configuration files (CI/CD, Dockerfile, IDE settings) may need corresponding updates to fully complete the Java 11 migration.
