fix: remove location manager and update listener on pause

Description (required)

Fixes #6480

What changes did you make and why?

When we navigate to Explore -> Map, it registers LocationManager and LocationUpdateListener, which keep track of location changes and call handleLocationUpdate, which further calls isNetworkConnectionEstablished, which is a method overridden by ExploreMapFragment, and it is supposed to access the context using the requireActivity method.

However, when we navigate away from the ExploreMapFragment, it becomes detached from its Activity. Despite this, the LocationManager continues to hold a reference to the fragment since it implements LocationUpdateListener. As a result, when the app is relaunched and opens the Contributions screen, background location updates still try to access the detached fragment’s context, causing an IllegalStateException.

To fix this, I now unregister the LocationUpdateListener and LocationManager in onPause(). This ensures location updates stop when the fragment is no longer visible (such as when navigating back), preventing memory leaks and invalid context access.

Note: It also fixes a memory leak caused by ExploreMapFragment.
