Add InstantPage.allMedia() (recursive gatherer over the page's blocks —
audio/collage/cover/details/image/list/slideshow/video — resolving each via
the page's [MediaId: Media] dict) and feed it into tagsForStoreMessage, so a
rich message's instant-page media is indexed into MessageTags
(photo/photoOrVideo/video/gif/voice/file). Rich messages now appear in the
per-peer shared-media tabs and tag-queried surfaces.
