chore(audit-live): add V2 (Leptos) explorer to surface

V2 (scan.sentriscloud.com + scan-testnet.sentriscloud.com) was missing
from the live audit surface. Both stay live alongside V1 per ops
direction; the audit needs to monitor both. Renamed v1 entries with
explicit `-v1` suffix for symmetry.

Verified locally: clean across all 17 surface URLs.
