Follow-up: Additional observability dashboard improvements (from PR #169)

[mchestr]

Follow-up tasks from PR #169

Tasks

• Add caching to getObservabilityData() server action using unstable_cache to reduce database load when multiple admins view the dashboard
• Use Next.js <Image> component for user avatars in active sessions panel with proper domain allowlist for security
• Add date range filters for activity trends (7/14/30 days toggle)
• Consider WebSocket support for real-time updates instead of polling (significant architecture change)

Context

From code review comments on PR #169:

For a high-traffic admin dashboard, consider adding caching to the server action using unstable_cache with 30 second revalidation to prevent hammering the database if multiple admins view the dashboard simultaneously.

If session.userThumb comes from user-controlled Tautulli data, it could potentially be a non-image URL. Validate image URLs or use Next.js <Image> component with proper domain allowlist.

Consider adding date range filters for activity trends (7/14/30 days)

Closing as low value. The dashboard works fine. Adding caching, Next.js Image components, and WebSocket support is over-engineering for an admin dashboard.
