- Added an Observability back-link at the top of all 7 Observability-area pages (AuditLog, SystemLogs, SystemInfo, AiUsageReport, UsageQuota, BannedIps, Diagnostics/Index) consistent with the Maintenance back-link pattern from PR 2
- Renamed company-level nav label and view title from "Notification Log" to "Email & SMS Log" to distinguish it clearly from the platform-level "Platform Notifications", "Audit Log", and "System Logs" surfaces
