Midman - P2P escrow for every deal

Roblox163 Midman intermediates every P2P trade. Buyer funds stay in escrow until delivery is confirmed - then the seller is paid.

1. Create a ticket - Buyer sets the amount and seller. Funds are locked into Midman escrow.
2. Seller delivers - Trade in chat under site supervision, then mark delivered.
3. Buyer confirms - Escrow releases payment to the seller. Dispute if something goes wrong.
