Merge #208: chore(deps): migrate svelte-sitemap from CLI to Vite plugin

c179bb2 chore(deps): migrate svelte-sitemap from CLI to Vite plugin (Jose Celano)

Pull request description:

  ## Summary

  Migrate svelte-sitemap from the deprecated CLI postbuild script to the recommended Vite plugin. This eliminates the deprecation warning on every build.

  ## Changes

  - Add `svelteSitemap({ domain: 'https://torrust.com/' })` plugin to `vite.config.ts`
  - Remove `postbuild` script from `package.json`

  ## Checklist

  - [x] `npm run lint` passes
  - [x] `npm run check` passes
  - [x] `npm run build` succeeds — sitemap now generated via `Method: Vite plugin` (no deprecation warning)
