feat(deployment): add GRT token tasks (status, balance, transfer, mint)

Hardhat tasks for managing testnet GRT:
- grt:status: show governor, minter status, total supply
- grt:balance: query GRT balance for any address
- grt:transfer: send GRT from deployer's balance (no minter role needed)
- grt:mint: mint new GRT (requires minter role)
