fix: the page connects to its own origin and reCAPTCHA, nowhere else

connect-src drops https: and wss: in both policies. Checked against Google's
reCAPTCHA test keys: in Chrome widget, token and registration unchanged; in
Firefox the widget loads; no violation reported in either.

A CSP contains exfiltration — `connect-src` names the page's own origin and reCAPTCHA's, nothing else — but cannot prevent injected inline script, so escaping is the actual fix. The reCAPTCHA hosts in `script-src` remain a known gadget risk: a nonce policy would remove it, and the application's page, served from disk, cannot carry one |
 | **H3** | **No public key is ever fetched from a directory to wrap a group key for.** The node wraps for a key the recipient proved possession of, bound to an account by a code the hub never sees (§3.4) |
 | **H4** | Revocation reaches nodes, drops live sessions, and **persists across a restart** (§7.5) |
 | **H5** | An admin challenge is a **structured, domain-separated transcript naming the operation and subject**, and the client refuses to sign anything that is not what the user asked for (§5.4) |
