Summary

This PR changes the sign-in flow to be more like Moonfin-Core. It shows the Quick Connect code in the main sign-in group itself, puts Quick Connect and Password in to tabs, and defaults to Quick Connect when detected in server.

Changes Made

• Moved Quick Connect from a dialog to be displayed on the signInGroup itself. This involved moving the functions from QuickConnectDialog to SigninScene. QuickConnectDialog.bs/.xml was removed since it is no longer used.
• Added 2 tabs, Quick Connect and Password, to switch between quick connect and the conventional username/password signInFormContainer.
• Added a check when initializing SigninScene to detect if Quick Connect is enabled on the server. If it is, we default to the Quick Connect tab.

Testing

• Tested on physical Roku device
• Tested via sideload
• Manual testing completed
• Not tested (explain why):
