refactor(ui): rename AuditLog viewer to ConfigurationAuditLog under /audit/configuration (#23 M7)

The pre-M1 IAuditService config-change viewer moves out of the Monitoring
nav group to make room for the new Audit nav group (issue #23 M7). The
old route /monitoring/audit-log returns 404 (no redirect, per plan) — the
viewer is now reachable at /audit/configuration and labelled
"Configuration Audit Log" to disambiguate from the new Audit Log page
(arriving in #23 M7-T9). Inbound references in NavMenu, Dashboard, and
the Playwright nav tests are updated to the new route and label.
