Fix/test cases fail reasons

[nikajorjika]

This pull request refactors the message store configuration to use a new inbox namespace, adds support for custom store resolvers, and updates the contract and tests for MessageStore. The changes improve flexibility in configuring storage drivers and make it easier to inject custom implementations.

Configuration and custom resolvers:

• The message store configuration is migrated from the old mailbox-for-laravel namespace to the new inbox namespace in config/inbox.php, including support for a new resolvers array for custom stores.
• The StoreManager class now checks for a custom resolver in inbox.store.resolvers before falling back to built-in drivers, using a new resolveCustomStore method.

Contract and test updates:

• The MessageStoreContractTest now expects the MessageStore contract to define update and clear methods in addition to existing methods. [1] [2]
• The StoreManagerTest is updated to use the new inbox configuration keys and tests custom store resolver logic, as well as the passing of configuration options to store implementations. [1] [2]
