fs 3053a77cde fix(security): prevent browser caching of dynamic pages
Add Cache-Control: no-store to all PHP-rendered pages so the browser
never serves a stale admin/auth page from its back-forward cache.
Static assets (CSS, JS, images) keep their 30-day expiry unchanged.

Uses fastcgi_hide_header to suppress PHP's default Cache-Control
before setting the definitive header via Nginx.
