perf(startup): defer offline sync and backup status until the grid is interactive

Browse Source 
Both fired during hydration and competed with rendering the grid, and the layout
waited for the user store before it could show a signed-in shell even though the
server already knew who the user was.

Seed the user from the layout data, and queue the offline sync and backup
refresh behind the grid's interactive mark; an explicit refresh, a reconnect or
an edit still runs straight away. Backup refreshes now share one in-flight
request per generation, and a change of account cancels the pending startup
refresh and clears the stale status.
