feat(ui): add clear queue flow and expose ISO expiry

- Add `formatBrowserTime()` and include ISO-8601 `expires_at` in box status JSON and `ExpiresAtISO` in the box view for browser-friendly rendering.
- Refresh UI styling (switch to MonoCraft/PixelOperatorMono, tweak base font size) and treat `aria-disabled="true"` like `disabled` for consistent button states.
- Introduce a clear-queue action with confirmation to reset upload state, unlock controls, and provide user feedback.feat(ui): add clear queue flow and expose ISO expiry
