Add Time Series / Monitoring View to Dashboard

[joshreini1]

Summary

Users running TruLens in production need to see how feedback scores trend over time — detecting regressions, drift, or degradation across app versions. Currently the dashboard only shows point-in-time aggregates.

What

Create a new Monitor.py tab (or add to Leaderboard) in src/dashboard/trulens/dashboard/pages/tabs/ with:

• Time series line charts of feedback scores over time (per app, per feedback function)
• Configurable time window (last hour, day, week, month)
• Score threshold lines / alerting bands (red/yellow/green zones)
• Version markers on the timeline (show when a new app version was deployed)
• Optional: anomaly highlighting when scores drop significantly

Data source: Records already have timestamps. Group by time bucket and compute rolling averages. Plotly is already available.
