Refactor the observer reports page from a static 3-tab layout to a
dynamic tab system that adapts to each round type (INTAKE, FILTERING,
EVALUATION, SUBMISSION, MENTORING, LIVE_FINAL, DELIBERATION). Adds a
persistent Global tab for edition-wide analytics, juror score heatmap,
expandable juror assignment rows, filtering screening bar, and
deliberation results with tie detection.
- Add 5 observer proxy procedures to analytics router
- Create JurorScoreHeatmap, ExpandableJurorTable, FilteringScreeningBar
- Create 8 round-type tab components + GlobalAnalyticsTab
- Reduce reports page from 914 to ~190 lines (thin dispatcher)
