Prevents sub-cent precision (e.g. $0.883125) from accumulating in
BalanceApplied and payment records. All balance math now rounds to
nearest cent first.

Balance from cash change now silently reduces the amount owed on the
next order. For cash: deducted immediately in submitCash, reduces cash
the worker needs to collect (or skips cash task entirely if fully
covered). For card: reduces the Stripe PaymentIntent amount, deducted
in webhook on successful payment. Receipt shows "Balance applied" line.

submitCash.cfm: Calculate platform fee from subtotal * PayfritFee,
store in Orders.PlatformFee and Payments.PaymentPayfritsCut on submission.
complete.cfm: Replace bogus 2.25% cash transaction fee with the real
platform fee (customer fee + business fee = 2 × PayfritFee × subtotal).
Credit full Payfrit revenue to User 0. Record business fee in
PaymentPayfritNetworkFees.

PaymentFromCreditCard column is NOT NULL with no default value,
causing INSERT to fail silently. Set to 0 for cash payments.

Payments table still uses old prefixed names (PaymentID as PK, no UUID
column, no PaymentTip column, required PaymentReceivedByUserID). Updated
INSERT to match actual production schema.
