Retrieves the blockchain deployment status of a Token Registry smart contract using the transaction hash.

This endpoint checks the transaction receipt on the Stability chain to determine whether the deployment transaction has:

• Successfully deployed the contract
• Is still pending
• Or has failed

Unlike role or permission operations, this endpoint performs a read-only blockchain lookup. No transaction signing or wallet authorization is needed.

Deployment Status Workflow

1. User provides a txnHash (transaction hash) via query parameters.
2. System validates that the transaction hash is a valid 32-byte hex string.
3. Based on the receipt result:
   • If no receipt is found → Status is Pending (transaction not yet mined).
   • If receipt exists and status = 1 and contractAddress exists → Deployment Success.
   • If receipt exists but status = 0 → Deployment Failed.
4. The result is returned with details such as block number and deployed contract address (on success).

Requirements

• A valid 32-byte hex-encoded transaction hash.
• The transaction must correspond to a Token Registry deployment transaction.

This endpoint is essential for monitoring smart contract deployment operations triggered in asynchronous workflows, UI progress trackers, or automated pipeline systems.
