Added a single isPaidStatus(status) (+ PAID_STATUSES) to statusService and a
matching client helper in trackerUtils, routing the unambiguous settled-status
checks through it (trackerService, StatusBadge, CalendarPage, rowIsPaid). The
intentionally paid-only counts stay distinct. Replaced two inline
Math.max(r.balance||0,0) with rowOutstanding, and gave the Tracker settings
load a quiet toast instead of a silent swallow. Behavior-preserving.
