Testing instructions

• Build Premium Analytics and its dependencies with fnm exec --using=24.15.0 pnpm jetpack build plugins/premium-analytics --deps.
• Open Premium Analytics and navigate to the Videos report.
• Select a date range without comparison and verify the records table shows video titles, Plays, and Impressions without a performance chart or comparison deltas.
• Enable date comparison and verify matching videos show change values for both Plays and Impressions.
• Verify linked video titles still open their video detail pages with the selected date window.
• Automated verification completed: 24 focused Jest tests, ESLint, Prettier, package typecheck, package build, and the full dependency-stack build.

Pull request overview

This PR updates the Premium Analytics Videos report to remove the performance chart and rely solely on a comparison-aware records table backed by the complete-stats summary request, while preserving video-detail linking and enabling plays/impressions deltas when comparison rows match.

Changes:

• Remove the Videos report performance chart (and its chart-specific aggregation / interval handling) and render only the records table.
• Switch the Videos report data source to a single comparison-aware complete-stats summary request; enrich comparison rows to include both previousPlays and previousImpressions.
• Update the table fields to render metric deltas via MetricWithComparison, and adjust/add Jest tests accordingly.
