Hide Logs button for unrun jobs; remove inbox filter bar; bump to 1.8

- Checks: only show the Logs button once a job has actually run (terminal
  conclusion). Queued/running jobs are grey with no logs, so the button was
  useless there.
- Inbox: remove the segmented filter bar (All/Assigned/By me/Review) — not
  useful yet. Bump to 1.8.
