v4.53.0 — Every Photo Lands

iPhone photos now always take. Some iPhones hand over a HEIC photo with no file-type label attached, and the uploader used to turn those away before it even looked at the ".heic" on the end — so a perfectly good shot got rejected for no reason you could see. It now checks the name too, and the photo goes through. The rest of this update is under the hood: the operator tools that re-run stuck jobs are stricter about never re-mailing a verification code that's already been used or has expired, and never re-sending one that a newer code replaced; a plain welcome or notice email can always be safely re-sent; a reward that's genuinely stuck can be nudged while a healthy one is left alone; and the admin screens keep telling the truth ("couldn't load — retry") instead of showing a fake-empty readout. Nothing else changes for collectors.
