Subject: [PATCH] Replace deprecated PropertyNamingStrategy with
 PropertyNamingStrategies

Jackson 2.21 removed the deprecated inner classes from
PropertyNamingStrategy (e.g. SnakeCaseStrategy). This breaks
any downstream project that upgrades to Jackson 2.21+ (via
Spring Boot 3.5.13+) with a ClassNotFoundException.

Migrate all @JsonNaming annotations to use the replacement
PropertyNamingStrategies class, which has been available since
Jackson 2.12.
