List download-only titles under Not supported, soften the human-check hint

Shadowmount titles can't take a patch, so they no longer sit under Updates.
They move to Not supported and keep their download: Download for Sony
updates, Old FW download for patches from Prospero. Fake packages stay
without any download.

Prospero's human check usually passes without the user noticing, so the
guide now only asks to confirm it if one shows up.
