Pull request overview

Adds a lightweight abstraction for treating async callables as Service instances, along with a default Service.name derived from the class name. Updates existing service-manager unit tests to avoid clashing with the new Service.name attribute and introduces new unit tests for CallableService and adapters.

Changes:

• Add Service.name base property derived from the class name.
• Introduce CallableService, ServiceLike, and as_callable_service adapter.
• Update unit tests and add new tests covering the new abstractions.

• Top-level logicblocks.event.processing re-exports CallableService but not the other newly added public helpers (ServiceLike, as_callable_service) that are exported from logicblocks.event.processing.services and mentioned in the changelog. If these are intended to be part of the main processing API, add them to the imports and __all__ here for consistency with the other service-related exports.
