fix: isolate SvelteKit-specific imports for library usage

Split SvelteKit-specific code into separate files to allow
windmill-components to be used as a library in non-SvelteKit
contexts (e.g., windmill-react-sdk):

- Split logout.ts into logout.ts and logoutKit.ts
- Split svelte5Utils.svelte.ts into svelte5Utils.svelte.ts and
  svelte5UtilsKit.svelte.ts (for runed/kit useSearchParams)
- Fix triggers/utils.ts type-only import resolution
- Update FlowRestartButton to use callback instead of direct navigation
- Update all route files to import from logoutKit
