fix: credentials lost on refresh + admin UI improvements + CI safe deploy

- dashboard layout: wait for Zustand _hasHydrated before redirecting to /login
  (was redirecting on first render before localStorage was read)
- admin shell: same fix using new _hasHydrated on admin auth store
- admin-auth.store: add _hasHydrated + onRehydrateStorage to mirror merchant store
- AdminPlansScreen: replace direct cache mutation with per-plan PlanCard component
  that owns its own useState — fixes other plans disappearing after save
- AdminSettingsScreen: detect boolean values and render iOS-style Toggle switches
- AdminIntegrationsScreen: replace all <input type=checkbox> with Toggle switches;
  replace OpenAI model text input with <select> dropdown (gpt-4o-mini/4o/4-turbo/4/3.5)
- blog editor: fix form never syncing existing post data into state (editing was broken);
  all fields now use local form state, save uses form directly
- blog links: fix broken relative hrefs (website/blog/new → /admin/website/blog/new)
  and back button using proper Link components
- ci-cd: remove image prune step entirely — never removes containers or images
