The reCAPTCHA siteKey was incorrectly listed as a sensitive field, causing it to be redacted from system config responses for non-admin users. Logged-out visitors received no siteKey, so the contact form showed "Recaptcha site key not configured" and the Send button was permanently disabled. The siteKey is a public key by design — it must be accessible to all users to render the captcha widget. Only the secretKey requires protection, which it retains. Also remove the unused &edit= parameter from the committee contact markdown link generator; the contact-us route never consumes it.
