Zabb v0.6.1

Bug Fixes & Code Quality

Fixed

• BuildContext safety — all usages of BuildContext across async gaps now properly guard with mounted / context.mounted checks or pre-capture Navigator/ScaffoldMessenger before the await. Prevents rare crashes when a widget is unmounted mid-operation.
• Browse Files sound picker — selecting a custom audio file via the file browser was silently discarded because the dialog was dismissed before the file picker returned. The double-pop is removed; the dialog now closes once with the selected path.
• Invalid @override on _notificationSubscription field removed.
• Unused SecurityContext import removed from zabbix_api.dart.

Improved

• Replaced all print() calls with debugPrint() so debug output is suppressed in release builds.
• Removed three dead private methods: _showNotificationConfigScreen, _selectSoundFile(BuildContext), _buildSeveritySwitches.

Tests

• Fixed widget_test.dart: SharedPreferences was not mocked, causing assertions to fail.
• Added routing test: verifies LoginScreen is shown when the app is already configured.
