fix: feed current dasha into web marriage path and keep chart fences on failure (BUG-609, BUG-610, BUG-611)

Consultation was passing the birth mahadasha into event-class splits, so marriage hits stayed empty and timing still said 缔结. Read live MD/AD from dasha_sub_periods, derive activation copy from the split, and isolate fence failures so one bad varga cannot 500 the whole report.
