Persisted HEIC files and local files with an empty or octet-stream type
were classified as "other", so they did not count toward the 10 photo /
3 video limit. Both classifiers now recognise them by extension.
The Photos & Videos uploader and Extra Docs ignore a new selection while
the previous one is still being screened, and the vendor portal drops an
earlier pick whose video check finishes after a newer pick.
Also removes ticket keys from source comments.
Extra Docs advertised the 90-second limit but only checked type and size.
Both dispatcher surfaces now share one screening step (type, size, count,
duration), and the Completion Doc media tab and Extra Docs count the whole
work order's photos and videos rather than only their own tab's share.
Failed local uploads no longer count toward the limit.
