Extends the per-app Updates treatment to the fleet App Center → Overview →
Updates list, and folds the manual check into the status line so it's the one
canonical (secondary) affordance rather than a top-level tab button:
- updater-page.js: renderAutoCheckLine() now ends with a right-aligned "↻ Check
now" button (data-updater-action="check" — both surfaces already wire it).
- overview-manager.js: drop the "Check"/"Check now" button from the Updates tab
header (keep "Update all", only when updates exist); lead renderUpdates() with
the auto-check line.
- overview.css: .updater-autocheck wraps on narrow widths; .updater-autocheck-btn
sits right (margin-left:auto), smaller.
- app-tabbed-manager.js: friendlier no-data copy ("You're all caught up — no
updates found for this app.").
