Fix: Map auto-recenters on fresh install and after enabling location services

- Fixed requestLocationIfNeeded() to use askForLocationPermission() which properly
  triggers activityResultLauncher callback (was using ActivityCompat.requestPermissions
  without handling the result)
- Fixed locationPermissionGranted() to call populatePlaces() after centering map
  to load markers at user location
- Added explicit location state check in onResume() to detect when location services
  are enabled while app is in Settings
- Added drawMyLocationMarker() call to show blue dot immediately after permission grant

Fixes commons-app#6599
