Rewrite report.query_store_regressions TVF with bounded baseline (mirror window instead of unbounded), execution-count weighted averages, multi-metric detection (duration/CPU/reads >25%), absolute minimum thresholds, and total impact ranking (additional_duration_ms). Deployed to sql2017-sql2025. Add double-click drill-down from regressions grid to QueryExecutionHistoryWindow. Add new grid columns: Total Impact, Base/Recent Exec Counts, Base/Recent Plan Counts. Fix chart:grid ratio to 3*:2* with MinHeight 300 across all drill-down windows. Lower sparse data threshold from 10 to 1 so lines always connect with 2+ points. Fix QueryExecutionHistoryWindow sparse threshold to use total count not per-plan count. Fix tooltip registration to collect scatters in loop instead of GetPlottables().
