**Steps to reproduce:**
* Install the **Manufacturing** module with **Work Orders** enabled.
* Create and confirm a Manufacturing Order with at least one Work Order.
* Open the **Shop Floor** view.
* On a work order card, click the **gear** icon to open the menu dialog.
* Click **Open Manufacturing Order** on a slow network connection.
* Before the MO form view finishes loading, quickly click the **gear** icon again and open another dialog (e.g. Log Note).
* The MO form view loads, destroying the shop floor component.
* Close the Log Note dialog.

**Observed behavior:**
* An `UncaughtPromiseError: Component is destroyed` error is thrown because the dialog tries to interact with the shop floor component that has already been destroyed by the navigation to the MO form view.

**Cause:**
* When the user clicks "Open Manufacturing Order", `doAction` is called to navigate to the MO form view, and `props.close()` immediately closes the menu dialog. However, the shop floor component is still visible while the new view is loading.
* During this gap, the gear button remains clickable. If the user opens another dialog (e.g. Log Note), that dialog holds a reference to the shop floor component. When the MO form view finishes mounting, the shop floor is destroyed, and closing the stale dialog triggers operations on the destroyed component.

**Fix:**
* Add an `actionPending` state flag to `MrpDisplayRecord`. When the user selects "Open Manufacturing Order" from the menu dialog, an `onSelect` callback sets `actionPending` to `true`, which disables the gear button and prevents any new dialog from being opened.
* The flag is only set for `openMO` (which navigates away and destroys the component), not for other menu actions like Scrap, Add Component, or Log Note which open wizard dialogs and return to the shop floor.
