ui: maximize button on the log viewer

The LogViewer header now has a maximize toggle (and a clear button) — maximize
expands it to a full-screen overlay (Esc to restore), so you can read service/
job logs without the 24rem cap. Consolidated the per-page 'Logs' Clear button
into the viewer header (both service and job detail pages).
