core, web: pin, archive and reorder a note someone shared with you

Schema v12 adds notes.state_at: a recipient's own pin, archive and order are
stamped there instead of on updated_at, which stays the text's time. Push sends
them only to a server advertising `shared_state` (push::Accepts), a view share
included; the first pull at that level starts the feed over once so held copies
drop their owner's pins. The client speaks protocol 7 and lists `shares` and
`shared_state` among the features a server may lack.

The web card and editor offer pin, archive and drag on shared notes; share and
trash stay the owner's, and the board's trash key skips notes you don't own.
