Surface rate-limit usage in the tray, mirroring the header/mobile usage view.
- New "Usage (Used/Remaining)" submenu groups enabled providers with their
window limits (e.g. 5-Hour, Weekly Limit, Credits) and per-window values,
reusing the quota store and the same formatting helpers as the rest of the UI.
- Honors the "configured to show" rule: only providers the user enabled for the
dropdown and that report as configured are shown; when none qualify the submenu
is omitted entirely.
- Tray-side data: build usage groups in useTraySync, push on quota-store changes,
do one initial fetch for enabled providers on launch, and refresh on a
desktop-only interval that respects the user's auto-refresh setting (no change
to web behavior).
- Rows are read-only (greyed) info items; provider flush, windows indented.
- Show the first 8 sessions inline and move the rest into the overflow submenu.
