Add utility to list all entities registered with DynamicRelations #43
Description
Is your feature request related to a problem? Please describe.
There is currently no easy way to see which entity classes are registered or managed by DynamicRelations at runtime.
Describe the solution you'd like
Provide a utility method (e.g., DynamicRelationsUtils.listRegisteredEntities()) that returns a list of all entity classes currently registered with the system.
Describe alternatives you've considered
Manually tracking entities or inspecting configuration files, which is less user-friendly.
Additional context
Example usage:
List<Class<?>> entities = DynamicRelationsUtils.listRegisteredEntities();This would help with debugging and verifying correct setup.
