RunCenter had three useEffects juggling log-chunk loading, tailing, and
older-chunk fetches. Move the whole lifecycle into useRunLogs, which
uses a single effect + AbortController to scope every IPC call to the
current run and pauses polling while document.hidden.
Remove "Create status report on schedule" default automation rule that
was creating empty draft documents every 60s. Simplify Runs page by
removing 3 summary cards and replacing 10-card metadata grid with
compact row layout.
