feat(analytics): integrate Umami analytics

This commit introduces Umami analytics for website usage tracking.

- Adds a new `analytics.js` file to the `public` directory to load the Umami tracking script.
- Updates `nuxt.config.ts` to inject this script into the document head and configure the page title.

Additionally, this commit fixes the referrer note display by removing a hardcoded prefix.
