fix: resolve frontend build failures in CI

- Remove noautoinject Wails scripts from config.html (Vite 6 requires
  type="module" on all script tags; Wails auto-injects them anyway).
- Replace vite-tsconfig-paths plugin with Vite native resolve.alias,
  fixing path alias resolution that was silently broken during builds.
- Remove unused vite-tsconfig-paths dependency.
