fix(engine): D9 double-transit targets check the D9 signs they name (BUG-1060)

`cmd_double_transit_pac` placed the `D9_{N}宫` target on the D9 lagna sign
and the `D9_{lord}(宫主)` target on that planet's D1 longitude. Both now sit
on D9 signs (D9 house-N sign; the lord's navamsa sign), built in one
testable helper. Target names, D1 and Chandra Lagna layers are unchanged
(pre-fix golden, byte-identical). Evidence-card golden regenerated with the
capture script (one public chart: double-transit conclusions 9 -> 10).
