feat: wire build/test infra, trips API, and enriched journey stops

- Add tsconfig.json (server) + client/tsconfig.{json,app.json,node.json}
  so typecheck and tsc -b actually work.
- Fix npm test to run Playwright (was running vitest on Playwright specs);
  typecheck now covers both server and client.
- Mount routes before app.listen, add error handler, mount optional
  @tonycodes/auth-express middleware when AUTH_SECRET is set.
- Add /api/trips (GET/POST/PATCH/DELETE) backed by an in-memory store
  that gracefully degrades when DATABASE_URL is unset.
- Add prisma/seed.ts skeleton and server/types/express.d.ts for req.auth.
- Rewrite Grok prompt for combo-aware planning: charge+eat,
  stay+destination-charging, eat+viewpoint, etc., with amenities,
  cuisine, priceLevel, duration, day titles and trip highlights.
- Extend Stop schema + normalization to preserve all enrichment fields.
- New StopCard component renders combo pill, description, meta row
  (charge / stop / battery / cuisine / £-level) and amenity icons;
  map popups show the same enriched detail; timeline gains day titles
  and a HIGHLIGHTS sidebar.
- Fix server TS errors (vehicle accepted as string | {name,rangeKm},
  JSON parse results typed).
