Fix IllegalArgumentException when dismissing ProgressDialog in destroyed activity

[cursor]

Problem

progressDialog.dismiss() was being called in async OkHttp callbacks without checking if EmpowerPlantActivity is still attached to the window manager, causing crashes when users navigate away before network requests complete.

Root Cause

1. IllegalArgumentException thrown when dismissing a ProgressDialog whose window has been detached
2. progressDialog.dismiss() called in OkHttp async callbacks (onResponse/onFailure) on a background thread after the activity may already be destroyed
3. No guard checks whether the hosting Activity is still alive (isFinishing/isDestroyed) before dismissing
4. User navigates away from EmpowerPlantActivity while a network request (fetchToolsFromServer or checkout) is in flight, causing the activity to be destroyed before the callback fires

Solution

Added safeDismissProgressDialog() helper method that performs the following checks before dismissing:

• Fragment is added to activity (isAdded())
• Activity exists and is not null
• Activity is not finishing (!isFinishing())
• Activity is not destroyed (!isDestroyed())
• Dialog is showing before dismissing

Updated all progressDialog.dismiss() calls in OkHttp callbacks to use the safe dismissal method wrapped in runOnUiThread():

• fetchToolsFromServer() onResponse and onFailure callbacks
• checkout() onResponse and onFailure callbacks

Also removed a duplicate progressDialog.dismiss() call in fetchToolsFromServer().

Testing

The fix prevents IllegalArgumentException crashes when:

1. User opens EmpowerPlantActivity (loads product list via network request)
2. Immediately navigates back before the network request completes
3. The OkHttp callback fires and attempts to dismiss the progress dialog

The dialog will now be safely dismissed only if the activity is still alive and attached.
