GamepadSettingsView gains a trailing Profiles section (one row per catalog
profile, live pinned-to-N-hosts counts) and an in-place pin-to-hosts picker
driving HostStore.setPinned — the first pin management reachable from the
controller-first UI, and on tvOS the only possible one. tvOS wording drops
the 'create them in the standard interface' promise (no profile editor
exists there); other platforms keep it. Pinned-card rendering and the
connect path were already in from WP5 and stay untouched.
