the accounts created are:

• Pool wallet Delegate Stake Account for the miner, (this is where all the Ore is put as it is mined)
• Managed Proof Account, For managing the ore proof account for delegated stake.
• Ore Proof Account, the actual proof for mining (Controlled by the Managed Proof Account)
• Managed Proof Ore Token Account, for when stakers stake it has to go through this token account.
• Pool wallets Ore Token Account (This one might not be necessary anymore actually)

How do I modify the code if I don't need an Proof account and only use the server account

How can I close these accounts and get solana back? This is very important to me, please help me
