refactor(vue): migrate app, routes, and tooling from Svelte

Replace the Svelte runtime, Vite plugin, Storybook adapter, and component files with Vue 3 equivalents while preserving the existing route table, page markup, styling, assets, deployment shape, and npm workflows.

Move shared and page-level state onto Vue refs, computed values, lifecycle hooks, and script setup components. Recreate the custom async router and translation composable as Vue-native modules so navigation and bilingual content continue to work without introducing a router or state-management dependency.

Adopt the maintained @lucide/vue package, remove the Svelte icon and map wrappers, and initialize MapLibre directly on the Helpdesk page. Replace the Svelte CSF story with a Vue Storybook story, remove obsolete aliases and generation/config files, and update the audited lockfile with no known vulnerabilities.
