Subject: [PATCH] Migrate from Java 8 to Java 11 with Spring Boot 2.7.18

- Updated java.version from 1.8 to 11 in pom.xml
- Upgraded Spring Boot parent from 2.1.4.RELEASE to 2.7.18
- Upgraded Springfox from 2.9.2 to 3.0.0 (springfox-boot-starter) for Spring Boot 2.6+ compatibility
- Updated test dependencies from JUnit 4 to JUnit 5
- Added BeanPostProcessor workaround for Springfox 3.0.0 compatibility with Spring Boot 2.6+
- Added path matching strategy configuration in application.yml for Springfox compatibility

All tests passing with the new configuration.
