fix(web): harden BFF auth — adversarial-review fixes
Multi-agent security review of 9856c04 (4 dimensions, 2-skeptic verification):

- CRITICAL functional+security: the session cookie inherited h3's Secure=true default;
  browsers DROP Secure cookies over plain http://, so login silently failed on a LAN HTTP
  client (worked only on localhost, a secure context — which is why the live test passed).
  Now set the cookie attributes explicitly: HttpOnly + SameSite=Lax + Path=/, and Secure
  only when PUNKTFUNK_UI_SECURE=1 (behind TLS). Verified: Set-Cookie no longer has Secure.
- Gate bypass: isPublicPath allowlisted any path ending in .json/.css/.png/etc., so
  /api/v1/openapi.json (served unauthenticated on the mgmt side too) leaked the whole API
  schema through the token-injecting proxy. Now /api is ALWAYS gated and the generic
  extension allowlist is gone (client assets are all under /assets/, still allowlisted).
  Verified: /api/v1/openapi.json and /api/v1/status.json → 401.
- Session lifetime: added maxAge (7d) — bounds a stolen cookie (cookie Max-Age + iron seal
  TTL); previously never expired.
- Open redirect: the post-login `next` accepted protocol-relative `//evil.com`. Hardened
  client + added safeNextPath() (same-origin path only).

Re-validated end to end: login assets public (200), /api/openapi.json gated (401), authed
/api/v1/status (200), unauth /→302. tsc + build green.
