Employee version dates now appear in familiar local formats, such as "Jan 1, 2000" in the US and "1 janv. 2000" in French. This makes HR information easier to read and more consistent for users in different regions.

This update adds automated tests for several Point of Sale data models, including orders, order lines, categories, and presets. These tests help catch regressions earlier and improve confidence in future POS changes without altering day-to-day user workflows.

Add hoot tests for POS models including `pos_order`, `pos_order_line`, `pos_category`, and `pos_preset`.

Users are now notified when an IoT-connected device is disconnected instead of actions simply failing silently. This makes device issues clearer and helps users understand why an operation could not be completed.

If a device is disconnected, we had no way of telling the user, we only didn't perform the action.

Now we notify the user that the device is disconnected.

Point of Sale users in Belgium now see a clearer disconnection message when the fiscal blackbox cannot be reached through the IoT Box. The dialog includes a retry option, helping staff continue order validation or clock in/out once the connection is restored.

We improved the dialog telling the user its blackbox is disconnected from the IoT Box.

We added a retry button to allow retrying validation of an order and clocking in/out.
