- Workaround for ElementHost bug

- Include localization .dll folders when packaging

- Thanks @DuckSoft for the review suggestions

- Since we now use System.Version, it's no longer needed.

- Infrastructure: use one HttpClient instance throughout the lifecycle
- Version update: rewrite the update service and add update prompt window
- Server sharing: add copy link button
- Dependencies: add ReactiveUI.Events.WPF, ReactiveUI.Fody, ReactiveUI.Validation, WPFLocalizeExtension, MdXaml

- Configuration: geositeDirectGroups + geositeProxiedGroups + geositePreferDirect
- PAC: rule generation using these new groups + cleanup

- Validate geosite group configuration
- Reset to default if specified group doesn't exist
- Regenerate pac.txt on version update (can be turned off)
- Cleanup of `Configuration` to separate loading logic and processing logic

- Fixes #2986

- Remove StringEx.CS
- Update all dependencies
- Eliminate all warnings

- For OnlineConfigResolver and GeositeUpdater

- Use ElementHost in QRCodeForm
- Cleanup: Server.Equals

- PAC proxied list only contains domain names from geolocation-!cn without a `cn` attribute

proposed by Stzx

- Deserialize the configuration using a constructor to set default values and initialize objects
- Re-enable the UI when online config update failed
