New client/types.ts domain-types module. Types the full /tracker response —
TrackerResponse { summary, bank_tracking, cashflow, rows } — with every money
field branded `Dollars` (the server serializes cents→dollars, verified against
statusService.buildTrackerRow + trackerService.getTracker + buildBankTracking +
buildSafeToSpend). api.tracker() now returns Promise<TrackerResponse>.
TrackerRow + TrackerStatus move to @/types (canonical) and are re-exported from
@/lib/trackerUtils for compat; trackerUtils' row money fields upgrade from plain
`number` to branded `Dollars` (rowThreshold -> Dollars, paymentSummary re-brands
its computed amounts via asDollars so callers can fmt() them directly). This is
the first endpoint where the money brand flows end-to-end: fetch layer -> row
helpers, and (in phase B) into the components that format them.
Nested payloads no typed consumer reads yet (summary.trend, autopay_suggestion/
_stats, sparkline) are left `unknown`, to refine when consumed. asDollars is an
identity at runtime, so behavior is unchanged: typecheck 0, lint 0 errors, build
green, 48 client tests pass.
