* Fix formatting problem in `zerotier-cli` when using SSO networks.
* Fix a few other minor bugs in SSO signin to prepare for general availability.
* Remove requirement for webview in desktop UI and instead just make everything available via the tray pulldown/menu. Use [libui-ng](https://github.com/libui-ng/libui-ng) for minor prompt dialogs. Saves space and eliminates installation headaches on Windows.
* Use system default browser for SSO login so all your plugins, MFA devices, password managers, etc. will work as you have them configured.
