fix: WIP: update did_generator.ts to use registration table
Changes: - Update SQL query to use registration table instead of accounts - Add proper column names for registration table schema - Add issuanceDate sorting for latest admin DID - Improve error messages for database queries - Add TypeScript types for database row results This fixes DID generation by using the correct table schema from the endorser database.

/**
|
||||
* DID Generator Script
|
||||
* @author Matthew Raymer
|
||||
*
|
||||
* This script generates and registers Decentralized Identifiers (DIDs) with admin authorization.
|
||||
* It supports the creation of Ethereum-based DIDs (did:ethr) and handles the complete
|
||||
* registration flow with the endorser.ch API.
|
||||
*
|
||||
* Features:
|
||||
* - Ethereum keypair generation using ethers.js
|
||||
* - JWT creation and signing using did-jwt
|
||||
* - DID registration with admin authorization
|
||||
* - Detailed error handling and logging
|
||||
* - Command-line interface for admin DID input
|
||||
*
|
||||
* Dependencies:
|
||||
* did-jwt: For JWT creation and signing
|
||||
* ethers: For Ethereum account operations
|
||||
* node-fetch: For API communication
