/// Picker shown when the user taps "Add connection".
///
/// When [targetProfile] is provided, also offers a "Borrow from another
/// profile" option that opens [BorrowConnectionScreen] for the target. The
/// global Connections screen invokes this without a target — Plex auto-
/// surfaces its Home users as new profiles, Jellyfin binds to the active
/// profile via [AddJellyfinScreen].
///
/// Pops with `true` after the underlying flow succeeds so the parent list
/// refreshes; pops with `null` (the default) when the user backs out.
