Thomas SharedInboxandClaude Sonnet 4.6 f7d021c62a fix: survive MissingPluginException on startup, fix crash report URL (#146)
Two fixes:

1. notification_service.dart: initNotifications() now catches
   MissingPluginException (and any other init failure) so the app no
   longer crashes when flutter_local_notifications is unavailable on
   some Android devices.  _initialized tracks success; showNewMailNotification
   skips the plugin call when it never initialised.

2. crash_screen.dart: "Report Issue on Codeberg" no longer puts the full
   report in the URL query string.  Long stack traces exceeded browser
   URL-length limits and caused "create issue failed".  The URL now
   carries only the pre-filled title; the user copies the full report
   via "Copy to Clipboard" and pastes it in the issue body.

Tests added:
- test/unit/notification_service_test.dart: verifies initNotifications()
  completes without throwing when the plugin channel is unavailable.
- test/widget/crash_screen_test.dart: verifies the Codeberg URL contains
  the title but no &body= parameter.
