The tracker row/status/sort helpers are now typed. Introduces a TrackerRow
domain interface (the fields these helpers read) and a TrackerStatus union
(paid|autodraft|upcoming|due_soon|late|missed|skipped). Row money fields stay
plain `number` for now — branding them Dollars is a later increment, done when
the tracker API response itself is typed so the brand flows in from the source.
Strict-mode handling: STATUS_SORT_ORDER is Record<TrackerStatus,number> (no
undefined on lookup); moveInArray guards the noUncheckedIndexedAccess `T |
undefined` from splice; the sort comparator relies on aliased-condition
narrowing to reach string|number in each branch. typecheck 0 errors, lint 0
errors (47 warnings unchanged), build green, 48 client tests pass.

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.
