Introduce ConnectionState enum (idle → authenticating → authenticated → destinationSelected → failed) replacing the old Bool isConnected flag. The entire UI renders reactively from this single state value. Authentication: vm.authenticate() drives the state, haptic feedback fires on success, any field edit resets back to idle so the user always knows their current auth is stale after editing. Connected banner: slides in below the credentials card after auth showing "Connected to [host]" with a green dot and a Disconnect button that resets state without clearing credentials. Destination row: always visible at 40% opacity with a lock icon and placeholder text "Connect to your NAS first" — activates to full opacity with chevron and browsable state after auth. Green border + subtitle "Backup destination ready" appears after selection. Taps blocked via allowsHitTesting until authenticated. CTA progression: idle/failed → "Connect" (enabled when fields filled) authenticating → spinner, disabled authenticated → "Choose Destination" (opens folder browser) destinationSelected → "Get Started" in green → navigates to dashboard After folder browser dismissal, confirmDestination() writes the path to ConnectionStore and fires a light haptic. Navigation to MainTabView happens only when state == .destinationSelected. Co-Authored-By: Kutesir <kutesir@provoc.ug> Co-Authored-By: Sentry <sentry@provoc.ug>
