feat(quota): All tab Command Code card shows Plan + 5h/weekly/monthly windows with reset times (v0.4.4)

- Tab order: All | Command Code | OpenCode Go (All remains the default)
- Drop the global status badge in the header action row and its
  updateGlobalBadge aggregation; per-card chips and All-tab provider
  badges are unaffected
