Ihor_Zhekov 070e1e6e09 fix(nginx): serve .txt as UTF-8 and make AI-discovery files reachable
llms.txt and robots.txt were served without a charset, so browsers
decoded the valid UTF-8 as Windows-1252 and showed mojibake (â€", für).

- Add `charset utf-8;` (+ charset_types) so text responses carry
  `; charset=utf-8`.
- Add an explicit `location ~* \.txt$` that serves the file as plain
  text, returns 404 instead of falling back to the SPA index.html, and
  sets `Access-Control-Allow-Origin: *` so any AI crawler/tool can fetch
  llms.txt / llms-full.txt cross-origin.
