feat(tajika): Mudda Dasha from natal Moon nakshatra + completed years, not the year lord (BUG-1216)

Ports calc_mudda_with_dasha_balance verbatim from upstream yinduzhanxing
c7117f92 (astrologer round-5 Q7). tajika_mudda.annual_mudda_dasha is the one
product entry for solar_return_full_report, cmd_tajika and full-reading
Step 9; periods are cropped to the Varsha year and carry months for the
month-window consumers. The consultation card re-anchors the engine's dates.
