fix(contacts): resolve Svelte 5 hydration error

- Move type exports from .svelte files to separate .types.ts files
  (FilterDropdown, CommandBar) to prevent SSR hydration issues
- Replace direct NetworkGraph component import in network store
  with TypeScript interface to avoid SSR component instantiation
- Add missing shared packages to vite.config.ts ssr.noExternal
  and optimizeDeps.exclude (splitscreen, i18n, profile-ui, etc.)

The hydration error "Cannot read properties of undefined (reading 'call')"
was caused by Svelte 5's stricter handling of component imports in
.svelte.ts files and type exports from .svelte files during SSR.
