fix(subs): resolve the plan version at the SALE instant, not validFrom

Browse Source 
Selling/quoting a subscription resolved the plan version against `validFrom`,
but validFrom is a DATE (midnight UTC for "starts today"). A plan published
later the same day (effectiveFrom 15:22) then failed `effectiveFrom ≤ validFrom`
(00:00), so resolvePlanVersion returned null → "no active plan for that planId",
and the form's selectedPlan went null (hiding the new count field too).

The plan/price in force is determined by WHEN THE SALE HAPPENS, not by the
coverage start — like a tariff, the customer buys today's published rate. Resolve
at new Date() in all three sites (validate, priceSale, /quote); validFrom is kept
only for span pricing. Verified the two live plans now resolve.
