v1.53.1 — Signed waivers keep their signature

A waiver signed on your booking page could lose its signature image about a day later, so printing it failed. The cause is fixed, every signature still on file has been moved somewhere safe, and a daily check now watches for it.

Signed waivers keep their signature. A cleanup job that clears abandoned half-finished signatures was also clearing finished ones. It now checks whether a waiver still needs the file before removing anything, and it never removes one that does.
Every signature you still have has been moved to safety — each one now lives with its own booking instead of in the temporary area, so nothing can sweep it up.
A waiver that has lost its signature says so on the page. It used to print a blank signature line, which looks exactly like a waiver nobody signed. It now prints a clear marker, and printing tells you who needs to sign again.
Something checks every day. If any signed waiver's signature ever stops resolving, we hear about it within hours instead of waiting for someone to press Print.
