Implement Miner Registration System

Summary

Implement the system for miners to register with mining accounts using keybooks.

Background

Third-party apps need to control who can mine by managing a registry of approved miners in a keybook.

Requirements

• Miner registration transaction type
• Registration fee handling
• Stake requirement enforcement
• Automatic expiry mechanism
• Maximum miner limits

Implementation Details

type RegisterMinerTransaction struct {
    TransactionBody
    
    MiningAccount   *url.URL
    MinerADI        *url.URL
    MinerPubKey     []byte
    StakeAmount     uint64
    RegistrationFee uint64
}

type MiningKeyBook struct {
    KeyBook
    
    RegistrationFee uint64
    RequiredStake   uint64
    AutoExpiry      uint64
    MaxMiners       uint32
}

Acceptance Criteria

• Registration transaction type defined
• Registration executor implementation
• Fee collection logic
• Stake verification
• Keybook entry management
• Expiry checking mechanism
• Maximum miner enforcement
• Unit tests for registration flow
• Integration tests with keybooks

Dependencies

• Depends on: #3669 (Mining Account Type)
• Depends on: #3666 (KeyPage Schema Updates)
