style(desktop): migrate bespoke pills to shared Badge; tidy cron/titlebar

- Sidebar toggles in the titlebar no longer carry an active highlight —
  they're plain show/hide affordances now.
- Replace every bespoke rounded-full status pill (cron, messaging,
  settings, skills) with the shared Badge (adds a `warn` tone). App radius,
  one component.
- Cron row actions use Codicons (play/debug-pause/zap/edit/trash) to match
  the rest of the chrome instead of stray lucide glyphs.
