Re-shoot the acceptance images at the current build

Both were taken at 20da315, one commit before the shadows were let out
of the namespace they had been reset in. Every resting shadow in the
app computed to none that day, so the notice pill in the reconnecting
shot is the one thing box 3 asks for and the shot could not show it,
and the tool cards in the chat shot were flat for the same reason.

The chat entry also now demonstrates the fallback it claims: the old
one captioned an entry "the photograph did not load" beside a handle
whose photograph loaded fine, so the rounded square that acceptance
asks for was nowhere in the image.
