will.anderson 3f3c5cf149 security: penetration test fixes — headers, cors, path traversal, info leakage 
- Switch to http_serve_v2/http_set_handler_v2 so request headers are available
  to El handler code (prerequisite for all header-based security checks)

- Stripe webhook (CVE-class): add HMAC-SHA256 signature verification against
  Stripe-Signature header using STRIPE_WEBHOOK_SECRET env var. Previously any
  unauthenticated POST could forge a payment_intent.succeeded event and
  increment the founding counter or trigger Supabase account provisioning for
  arbitrary emails.

- CORS on /api/supabase-config: restrict to neurontechnologies.ai and localhost
  origins only. Cross-origin requests now get 403.

- /api/soul-health: require X-Internal: true header; otherwise return 404.
  Endpoint was publicly accessible and leaked internal soul service URL,
  network topology, and raw probe responses.

- Static asset / JS headers: add X-Frame-Options, Referrer-Policy,
  Permissions-Policy, and Content-Security-Policy to static_asset_headers_json
  and js_headers_json. These were only present on HTML/API responses before.

- Fix state key bug: share_card_page read state_get("__neuron_origin__") but
  the key registered at startup is "__origin__", causing empty base URLs in
  share card og: meta tags.
