feat: add admin access monitoring for ArchiveOS routes

[CSJ-PJT]

Summary

• record ArchiveOS UI route visits with actor, role, client IP, route and timestamp
• preserve client IP through the OCI edge/frontend nginx path
• expose ADMIN-only access-log summary and history APIs
• add 설정 > 접속 기록 admin screen with 24h metrics, active visitors, route breakdown and recent access history
• retain access telemetry for 30 days and never store cookies, tokens, or request bodies

Safety

• feature branch only; no production/Golden frontend deployment
• no existing service or database data is deleted
• migration only creates web_access_logs

Validation

CI should run frontend, Node compatibility, Java runtime and compose validation. Local execution is intentionally deferred while the current host disk incident is being recovered.
