feat: 5128 - visible dates on raw image grid items

[monsieurtanuki]

What

• Now the upload date is displayed on top of raw image grid items.
• The background of the tag is white if not expired (less than 1 year old), or red
• That works only for products refreshed after the app upgrade, as we use a new field (upload timestamp) that wasn't retrieved before.
• In case we don't have an upload timestamp, we display no tag at all, only the image (like before).
• We should probably somehow display that upload date in other places, like the full uploaded image page.
• Probably also on the "main" images, but that could be source of confusion, because the last modified date of a main image may be very different from the upload timestamp of the underlying raw image.

Part of

• photo dates not visible on mobile, difficult to know the most up-to-date version #5128

Impacted files

• product_image_gallery_other_view.dart: display the upload date on top of raw image grid items
• product_image_gallery_view.dart: unrelated minor refactoring
• pubspec.lock: wtf
• pubspec.yaml: upgrade to off-dart 3.5.0 in order to get the uploaded timestamp of raw images
• smooth_image.dart: unrelated minor refactoring
