Retrieves human-readable ABI signatures for a specific smart contract. This endpoint fetches the contract metadata from the thirdweb service, extracts the ABI, and converts it into an array of human-readable function and event signatures that can be used directly with contract interaction methods.

Authentication: This endpoint requires backend authentication using the x-secret-key header. The secret key should never be exposed publicly.

Usage: The returned signatures can be used directly in contract read/write operations or event filtering. Each signature follows the standard Solidity format and includes function parameters, return types, state mutability, and event indexing information.
