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.

hooks/useQueries.js -> .ts. Typed params and QueryParams-typed query builders
(QueryParams now exported from api.ts). Query result data stays unknown until
endpoint response shapes are typed.
TypeScript caught dead config: three hooks passed `cacheTime` to useQuery, which
React Query v5 renamed to `gcTime` and silently ignores — so those caches were
garbage-collected at the 5-min default instead of the intended 30 min / 2 hr.
Renamed to gcTime so the intended retention takes effect (memory-retention only;
no fetch or correctness change).
Verified: typecheck 0, lint 0 errors (47 warns), build green, 48 client tests,
17/17 e2e probe (every page renders).

client/api.js -> api.ts. Types the fetch infrastructure: generic _fetch<T>
and get/post/put/patch/del<T> helpers, an ApiError interface (status/code/
details/data), a QueryParams type for the query-string builder, and File-typed
upload helpers. Endpoint response shapes are typed incrementally — most methods
default to Promise<unknown>; the ones consumed by typed .ts files get real
shapes (quickPay -> PaymentRecord, togglePaid -> TogglePaidResult, settings ->
settings map).
Typing togglePaid's result surfaced a latent narrowing bug in usePaymentActions:
the un-pay Undo closure read result.paymentId (number|undefined) inside a
deferred async callback where TS re-widens the if-narrowed value — fixed by
capturing the id in a const before the closure.
The 16 files importing '@/api.js' with an explicit extension were normalized to
'@/api' so Vite/TS resolve the .ts.
Verified: typecheck 0, lint 0 errors (47 warns), build green, 48 client tests,
and 17/17 e2e probe (every page renders, all API paths respond) — the central
fetch-module rename is runtime-safe.
