Merge origin/dev into codex/analytics-overview-filters

Resolve conflict in pill-toggle.tsx: preserve PR's animated slider
feature (useEffect hooks, ResizeObserver, refs) while incorporating
dev's TooltipProvider wrapper. Kept PR's conditional TooltipProvider
approach (only wraps when showLabels=false) and moved TooltipPortal
import to @hexclave/ui per dev.
