Live-update dashboard rows and show toasts after sync actions

"Sync now" and "Sync all now" now return the freshly reloaded rider
row(s) plus an out-of-band toast instead of navigating to a separate
result page. The "sync already running" case is a 200 + info toast
now instead of a 409 special case.
