chore(deps): update Flutter and Go dependencies to latest stable

Flutter: bump connectivity_plus, device_info_plus, share_plus, receive_sharing_intent, path_provider, flutter_local_notifications to latest stable. Revert file_picker from 12.0.0-beta to 11.0.2 stable and migrate pickFile (singular) to pickFiles. Add win32 ^6.0.1 dependency_overrides to resolve the win32 5 vs 6 conflict between file_picker stable and device_info_plus (Windows-desktop-only transitive dep, not used on mobile targets). Go: update goja, golang.org/x/mobile, golang.org/x/tools, regexp2/v2 to latest.
