Add CRUD methods for information blocks in ledger client

[jfrench9]

Summary

This PR extends the LedgerClient with new facade methods for managing information blocks, adding full create, update, and delete capabilities.

Key Accomplishments

• Added create_information_block method: Enables creation of new information blocks through the ledger client facade, providing a clean interface for consumers.
• Added update_information_block method: Supports updating existing information blocks by ID with new data.
• Added delete_information_block method: Allows deletion of information blocks by ID through the client.
• Maintains consistency with the existing client method patterns and API conventions used throughout the LedgerClient.

Changes

• robosystems_client/clients/ledger_client.py: Added 66 lines implementing three new public methods (create_information_block, update_information_block, delete_information_block) that expose information block management operations through the ledger client facade.

Breaking Changes

None. This is a purely additive change that introduces new methods without modifying existing interfaces.

Testing Notes

• Verify that each new method correctly delegates to the underlying API endpoints for information block CRUD operations.
• Test error handling for invalid or missing information block IDs on update and delete.
• Confirm that request payloads and response parsing align with the expected API contract.
• Validate that existing ledger client functionality remains unaffected.

Infrastructure Considerations

• Ensure that the backend API endpoints for information block management are deployed and available before consumers begin using these new client methods.
• No new dependencies are introduced; the changes leverage existing HTTP client infrastructure within the LedgerClient.
