[PublicDecks] Time out the loading state so a dropped reply cannot wedge the tab

Browse source 
loading only cleared in decksReceived, but the ping sweep can drop a pending
command without ever emitting finished, leaving the tab stuck on 'Loading
public decks...' and the refresh button permanently inert. A single-shot
timer started per refresh clears the latch and reports a timeout; the latch
also clears when the client disconnects.
