0c291ba feat: add blog post about new Torrust Tracker Demo (Jose Celano)

Pull request description:

  ## Summary

  Adds a new blog post announcing the launch of the dedicated Torrust Tracker Demo on Hetzner.

  **Post:** `/blog/new-torrust-tracker-demo`

  ## Content covered

  - Background: the original combined Torrust Demo (Tracker + Index) on Digital Ocean and why it was valuable
  - Why we split the demo into two independent projects (July 2025)
  - Building the Torrust Tracker Deployer before migrating — and using this deployment as its final end-to-end test
  - The new demo setup: Hetzner hosting, MySQL (instead of SQLite), IPv6 support
  - Observability: three Grafana dashboards (overview, UDP tracker, HTTP tracker) with screenshots
  - Submitted to Newtrackon — with a note about the IPv6 routing fix and uptime recovery
  - Why we share all of this: eating our own cooking, building for AI agents
  - What's next: three planned follow-up posts (deployment deep-dive, IPv6 floating IP, Newtrackon tips)

  ## Files added

  - `src/routes/blog/new-torrust-tracker-demo/` — post route (metadata, server loader, Svelte page)
  - `static/images/posts/new-torrust-tracker-demo/` — cover, Grafana screenshots, Newtrackon screenshot, infographic summary
  - `static/blogMetadata.json` — regenerated to include the new post
