Subject: [PATCH] Present instance login as full-screen cover on tvOS

The .sheet rendering on tvOS produced a tiny floating modal where the
"Sign In" title wrapped onto two lines and form fields overflowed. Use
.fullScreenCover on tvOS and wrap the login form in
TVSidebarDetailContainer so the title/icon sit in the standard 400pt
left sidebar. iOS and macOS keep the existing sheet presentation.
