Security: Send security headers; refuse to frame the dashboard
Pages carried no X-Content-Type-Options, no Referrer-Policy, and the
dashboard could be framed by any site (clickjacking a superadmin's
delete buttons). Every response now says nosniff and
strict-origin-when-cross-origin, and the management paths on the root
host add X-Frame-Options: DENY plus a CSP of frame-ancestors, base-uri,
form-action and object-src — the directives that do not touch the
dashboard's inline scripts, which are a product constraint. Blog pages
get no framing rule: they are the owner's content and may be embedded
on purpose. HSTS moves into the same helper.
