Say when rsync last moved data, and stop colouring successful runs red

last_sync reads the maintenance orchestrators' run records, and those do git
pull, permissions, cleaners and docker updates on schedule whether or not the
global gate is open — so the page reported a healthy 56-minute "daily sync"
while nothing had transferred since 16 July. Both cards also compared status
against 'success' while being fed 'ok', so every clean run rendered in the
failure colour. Adds the assistant, scoped to the tab.
