Prepare an unsigned transaction for Cardano staking operations.
Transaction Types:
- delegate: Start earning rewards by delegating to Stakefish pool
- undelegate: Complete exit from staking (withdraw rewards + deregister + get 2 ADA deposit back)
- withdraw: Claim accumulated rewards only (stake remains active and delegated)
Important Notes:
- Delegation takes 2 epochs (~10 days) to become active
- Undelegation is permanent - requires re-registration to delegate again
- Withdrawal claims ALL available rewards - partial withdrawal not supported
- All transactions require sufficient ADA in the payment address for fees
