Fixes on-chain withdrawal race condition in route.ts
Changes on-chain withdrawal flow to:
reserve balance atomically with updateMany({ walletBalance: { gte: amount } })
create pending withdrawal after successful reservation
refund reserved balance if submitStellarWithdrawal fails
Adds regression coverage in wallet-withdraw.test.ts
simulates two concurrent on-chain withdrawals that exceed available balance
verifies only one succeeds and wallet balance is not overdrawn
Verified with corepack pnpm --dir app exec vitest run tests/api/wallet-withdraw.test.ts
closes #349
