python3: Fix CVE-2026-3644 and CVE-2026-0672

Apply the upstream v3.13 fix [1], as referenced in [2], to address
CVE-2026-3644 by rejecting control characters in http.cookies.Morsel.update(),
the |= operator, and unpickling paths.

CVE-2026-3644 [2] revealed the CVE-2026-0672 fix was incomplete, as
Morsel.update(), |=, and unpickling could bypass input validation. The fix
also adds output validation to BaseCookie.js_output(), matching the
control-character safeguards already present in BaseCookie.output().
