Upgrade Runtime and Test Dependencies

Issue #, if available:

Description of changes:

This pull request upgrades project dependencies to current versions and removes several unused test dependencies.

Upgraded libraries include the following:

Upgraded Gradle from 8.1.1 to 8.6
Upgraded Jackson from 2.15.0 to 2.16.1
Upgraded SLF4J from 2.0.7 to 2.0.12
Upgraded JUnit from 5.9.3 to 5.10.2
Upgraded jqwik from 1.7.3 to 1.8.2

Changes and removals include the following:

Replaced Log4j 2 with SLF4J Simple implementation for testing
Replaced FindBugs 3.0.1 with SpotBugs 4.8.3
Removed unused Mockito Inline dependency
Removed unused SLF4J Reload4j

The slf4j-simple library defaults to writing INFO level messages to the console, which is the same behavior as the test Log4j 2 configuration. The slf4j-simple library also supports configurable logging levels using system properties, which supports options like trace levels when needed.

The FindBugs 3.01 library was released in 2015, and spotbugs-annotations provides the maintained version fork with the same annotations. The EntityUIDTests class had an unused import for org.apache.bcel.generic.IDIV, which was previously provided through a transitive dependency of FindBugs 3.0.1.

The mockito-inline dependency was not used.

The slf4j-reload4j library is a patched implementation of Log4j 1, which is not needed for testing with slf4j-simple providing console logging.
