Pull request overview

Updates the Gradle build’s Spring Boot dependency-version override properties to pin patched Jackson and PostgreSQL versions, addressing reported CVEs by ensuring the imported Spring Boot BOM resolves to the fixed artifacts.

Changes:

• Add version-catalog entries for Jackson 3.x, Jackson 2.x, and PostgreSQL JDBC driver.
• Wire those catalog versions into Spring Boot BOM override properties via extra[...] in the root build.gradle.kts.
