Fix connection status display in tests

When APRS connection is disabled (in test environment), the LiveView should
show 'disconnected' status instead of hardcoded 'connected'. This fixes the
failing aprs_status_test.

Add get_initial_connection_status/0 helper that checks the
disable_aprs_connection config to set the appropriate initial status.
