fix: resolve Badhaka house by lagna in curse yogas, drop death wording (upstream 6abfe983 follow-up, BUG-1192)

Preta Yoga hard-coded the 11th house as Badhaka; it now uses the single
yoga_engine.badhaka_house() definition (movable 11 / fixed 9 / dual 7).
Remaining early-death / lineage-ending phrases removed from curse yoga
family effects and the Matru-hani yoga effects list.
