fix: wire SOS button, emergency overlay, message bar and banner into map screen

These widgets existed as complete implementations but were never
added to the map screen's widget tree. Users could not see or
interact with tactical messaging or emergency beacon features.

Also fixed ConsumerState.build signature in sos_button.dart
(extra WidgetRef param prevented compilation when imported).
