🐛 fix: resolve auth issues in Manacore, Calendar, and Clock apps

- Manacore: fix import path for authStore (authStore.svelte → auth.svelte)
- Calendar: simplify root layout by moving PillNavigation to (app) layout
- Clock: update login page to use correct shared-auth-ui props (onSignIn, logo, goto)
- Add ClockLogo component to shared-branding package
