Fix Grafana config-sync: --exact-timestamps for same-size updates

Browse source 
aws s3 sync skips same-size files on download unless --exact-timestamps is set,
so a dashboard edit that doesn't change file size (e.g. refresh 2->1, or a query
tweak) never propagated to the instance. Add --exact-timestamps to all four
sync invocations (boot + 15-min timer).
