Build native image#29

Keycloak 22 is EOL; 26.6 brings hostname v2 with backchannel-dynamic support. Postgres 13 is EOL and unsupported by Keycloak 26. docker-compose.full.yml also gets hostname v2 config and parameterized ports so the browser-facing issuer URL stays in sync.
UniversalJwtDecoder extracts the issuer from tokens and fetches JWKS from that URL. In Docker, the browser-facing issuer (localhost:8010) is unreachable from the API container. The new issuer-overrides config maps external base URLs to internal Docker hostnames for JWKS fetching while preserving the original issuer for token validation.
Pass -PbuildNative to produce a GraalVM native image via buildpacks. Add build and launch cache volumes for faster repeat builds.
Builds both JVM and native Docker images on every push and PR. Native images get -native suffix tags (e.g. beta-abc1234-native).
- Use withJwkSetUri when issuer override is active to avoid issuer mismatch between Docker hostnames (token says localhost, API resolves via internal hostname) - Change JwtIssuerOverridesConfig from Map to List<IssuerOverride> to fix Spring Boot property binding with URL keys - Replace manual resource-config.json with RuntimeHintsRegistrar for Liquibase native hints (avoids conflict with AOT-generated file) - Make GraalVM plugin conditional (apply false + hasProperty check) so JVM builds use JRE instead of NIK
