docs: regenerate the gallery captures, Start-card thumbnails and setup-symbols picture for 0.6.0

Window captures (light theme, 1400 x 860) of every sample solved on the current UI; the
thumbnails that were viewport crops are now clean ui.render images like the others; the drop
test's figure at 0.1 ms reads 129 MPa.
