+ * Filter button for the Orders list. Opens a native <dialog> as a
+ * right-edge sheet (matching the MoreSheet pattern) with status options.
+ * Picking a status pushes a new URL with the `status` search param —
+ * the server component re-renders with the filter applied.
+ *
+ * The status values here are the v2 StatusPill vocabulary
+ * (placed/ready/picked-up/cancelled) which is what the orders page
+ * filters on. Empty string = clear filter (all orders).
