* Direct On-Chain NFT Mint
3+
*
4+
* This endpoint performs a direct mint by:
5+
* 1. Validating admin credentials
6+
* 2. Calling the RPC to prepare the mint
7+
* 3. Storing in local index
8+
* 4. Returning the result
9+
*
10+
* For true on-chain storage, the validator needs to process the mint transaction.
