Subject: [PATCH] feature: migrate to Java 21 (LTS) and modernize Docker base
 images

- pom.xml: java.version 17 -> 21, remove maven-compiler-plugin override
  (was forcing source/target 1.8); switch mysql-connector-java 8.0.33 ->
  com.mysql:mysql-connector-j (version managed by Spring Boot parent)
- Dockerfile: maven:3.8.3-openjdk-17 -> maven:3.9-eclipse-temurin-21 builder;
  openjdk:17-alpine -> eclipse-temurin:21-jre-alpine deployer
