fix(machine): auto-init HAL in production, wire dispense completion, add GTQ

- App.vue detects Electron and calls initializeForProduction() to start
  real hardware drivers instead of Lightning-only mode
- Auto-send CASH_DISPENSED when HAL is active since dispenseCash already
  waits for bills to be removed before resolving
- Add GTQ (Guatemalan Quetzal) bill lengths to F56 and Puloon dispensers
