Support cycling the log tail count from the services panel too

The services panel's Logs tab renders the underlying container's logs
through the same code path, so bind 't' there as well and include the
tail value in the services context cache key so the tab re-renders
when the value changes. Also switch the tail-limiting writer to
SetContent so the clear+rewrite is atomic and the view never renders
empty in between.
