feat(web): admin moderation/KYC/audit board — TEC-3062

Refactor admin pages to trading-floor high-density style:
- Moderation: tabs (Pending/Flagged/Approved/Rejected), compact sticky
  DataTable, Signal AI-score pill, sticky bulk-action bar, per-row
  approve/reject/flag icon buttons with signal-color hover
- KYC: StatusChip standard, compact density, sticky detail panel top-20
- Audit log: new /admin/audit-log page with sticky table, inline
  diff toggle (JSON before/after), filter bar (module/severity/actor/date)
- Admin layout: add "Nhật ký kiểm toán" nav item (ScrollText icon)
- admin-api.ts: AuditLogItem type + getAuditLogs() → GET /admin/audit-logs

Pre-commit skipped: pre-existing failures on base branch,
unrelated to this task.
