Every dict-returning route the SPA consumes now declares a response
model (auth, bulk, sync-status, notifications). api-types.gen.ts is
generated from app.openapi() via openapi-typescript, and the 22 hand-
written read interfaces in api.ts are now aliases onto the generated
schemas — backend schema drift becomes a typecheck failure, and CI
regenerates the file and fails the deploy if it's stale. The aliasing
immediately caught two real drifts: RecurringItemType was missing
SAVINGS, and raw_charges (untyped JSON column) is now explicitly
shaped at the boundary.

Budget: recurring items CRUD, yearly/monthly projections with no-double-count
logic, and full UI (overview, monthly detail, recurring items manager).
Push notifications: Web Push via VAPID keys, triggered on transaction creation
from n8n. Includes service worker handlers, frontend subscription flow, and
a test button on the Dashboard (temporary).
