"""sanitize_error must scrub IPv6 addresses, not just IPv4.
Webhook delivery errors are stored in Webhook.last_error and surfaced in the
UI. The scrubber removed IPv4 literals but let IPv6 addresses through, so a
failed delivery to an internal v6 host (::1, fe80::/fc00:: ...) leaked the
address. This pins the v6 redaction while keeping the false-positive guards
(clock times, MACs, C++ "::") that make the pattern safe on arbitrary text.
