fix(html-report): funnel from stage history, rejection rate from true rejections

The funnel was computed from current status - a state, not a history -
so an application that interviewed and was later rejected never counted
as reaching Interview, and a hired candidate produced Interview=0. The
stage checkboxes Step 1.2 already merges from outcome.md are the
history; Step 2 and chart 4 now use them. The rejection rate also
counted offer_declined (a success) and withdrawn (candidate-initiated)
as rejections and left unresolved Interview/Offer rows in the
denominator. Review findings F10 and F11 (2026-08-19).
