Frudrax Cheng 6a48b0624f Replace phone last-4 verification with customer signature ...

Customer now signs on the confirm page instead of inputting the last
4 digits of their phone. Signature is stored as a base64 PNG dataURL
on the work order and shown back to the customer plus archived for
admin review. Reject still bypasses signature but now requires a
reason.
