extendUserTier called setUserTier, which unconditionally zeroed monthly_consumed and re-anchored the cycle. A user who renewed mid-cycle (or a webhook double-firing across a restart) got their full monthly allotment back for free. The monthly cycle already rolls on its own anniversary via ensureRenewalRollover, so renewal must not reset it. Add resetCycle to setUserTier (default true, preserving operator-grant behavior); extendUserTier passes false for an in-force subscription and true only for a brand-new or lapsed one. Add regression tests.
