python3: Fix CVE-2026-4519 and CVE-2026-4786
Apply the upstream v3.12 fix [1], aligned with the original v3.11 fix [2],
and follow-up fix [3] to address CVE-2026-4519 by disallowing URLs with
leading dashes when invoking browser commands, as referenced in [5].
CVE-2026-4786 [6] revealed the CVE-2026-4519 fix was incomplete, as %action
in URLs could bypass dash-prefix checks. Apply follow-up fix [4], noted in
[5], to revalidate the URL after %action expansion.
