Remove Xide and ides.progmasoft.comfeature/remove-xide

Xide is no longer developed as of 2026-11-08 (Progmasoft/xide#29), so
Progmaweb stops presenting it:

- product.progmasoft.com: Xide leaves the catalog, its card and its
  detail page; /xide on the product host is a 404 like any unknown
  product. The catalog's description in every language names the Tala
  language with its tools and Catch3.
- ides.progmasoft.com served only the IDE list and the Xide page, so the
  whole site goes: the pages under app/ides, its texts in every
  language, idesRoute and its host in the proxy, and both nginx server
  blocks. The certificate of progmasoft.com no longer has to name it.

Tests: the catalog lists the remaining products and refuses xide.
