Subject: [PATCH] Fix Jackson 2.21 compatibility:
 PropertyNamingStrategy.UPPER_CAMEL_CASE removed

Jackson 2.21 (bundled with Spring Boot 3.5.x) removed the deprecated
static field PropertyNamingStrategy.UPPER_CAMEL_CASE, causing a fatal
NoSuchFieldError at runtime when NomadJson class initializes.

Migrate to PropertyNamingStrategies.UPPER_CAMEL_CASE (available since
Jackson 2.12) and update the compile-time Jackson version to 2.18.2.

This fixes PIM-7078 where slave server initialization crashes with:
  Exception in thread "Setup" java.lang.NoSuchFieldError:
  Class com.fasterxml.jackson.databind.PropertyNamingStrategy
  does not have member field UPPER_CAMEL_CASE
