What

• Add pull to refresh in the photo manager in edit mode

Why

• It's not refreshed automatically when the image upload is complete, leading the user to believe it did not work.

I was working on this workaround, for a while

• We change the placeholder images there immediately with the ones from file images that we have, till we delete them after the background process finishes,
• Use UptodateProductProvider to rebuild the whole product widget/gallery once the image upload task is done, I think Mr. Monsieurtanuki is working on that for now,
• Added benefits will be, even if the user is offline if he adds a picture it will show him immediately

If this approach looks okay, then I could probably go and make a fresh clean code pr for this feat.

Sounds good to me @AshAman999 but we should still add a pull to refresh gesture just that it's the same behaviour on all edit pages
