How Fee Claiming Works

Every buy and sell on a market accrues fees split 50/50: 
trade_fee   = trade_amount * trade_fee_bps / 10000
creator_fee = trade_fee / 2       → market.creatorFeesAccrued
pmx_fee     = trade_fee - creator_fee  → market.pmxFeesAccrued
When claimFees is called:
  1. The instruction checks if the wallet is the creator or the PMX wallet.
  2. The corresponding accrued amount (creatorFeesAccrued or pmxFeesAccrued) is transferred from the market vault to the caller’s USDC token account.
  3. The accrued field is reset to 0.
Fees can be claimed at any time — while the market is active, after resolution, or after cancellation. There is no deadline.
