Adds Category (+ CategoryBillSummary) to @/types and wires categories/
createCategory/updateCategory. Category has no money field of its own (budgets
live on the spending endpoints); the nested per-bill total_paid is a raw SQL sum,
so it's deliberately left unbranded. With categories now typed, useSpending
Categories drops its `any` cast and dead d.categories branch.
Category, Bill, Payment, and the Tracker envelope are the cross-cutting types
used by many components — worth defining upfront. The remaining single-consumer
page responses (summary, analytics, spending, snowball, subscriptions, bank
ledger) are typed alongside their page conversions in phase B, where the exact
fields consumed are visible (more accurate than a speculative interface).

Adds Bill and reuses Payment domain types (money → Dollars, mirroring
serializeBill/serializePayment which spread the DB row and convert the money
columns). Wired: bills/allBills/deletedBills → Bill[], bill/createBill/updateBill
→ Bill; quickPay/createPayment/updatePayment/restorePayment → Payment. Replaced
api.ts's minimal PaymentRecord with the richer @/types Payment (usePaymentActions
still resolves payment.id). typecheck 0, build green, 48 client tests.

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.
