Since the old name, Remote Inbox Notifications are used for functions that are general to Remote Specifications, we should deprecate all general classes under src/Admin/ using DeprecatedClassFacade:

We should also look for other repositories under Woo which may use the classes and update them, or notify repository owners.

Acceptance criteria

1. Deprecate above classes
2. Update all consumers in Core to use the new namespace
3. Update consumer in bridge (ensure it's deployed after Core is updated)
4. Optionally, look for other consumers across Woo repositories and supported extensions
