Subject: [PATCH] Implement missing RPC endpoints and fix GPU operations

- Add mining RPC endpoints: /rpc/mining/start, /rpc/mining/stop, /rpc/mining/status, /rpc/mining/miners
- Add pending transactions endpoint: /rpc/pending (alias for mempool)
- Update GPU register/update commands to not require island credentials
- All mining endpoints use in-memory storage for simplified implementation
