* feat(shared): add payment ladder and CSV domain package Introduce @seahaven-ap/shared via npm workspaces so FE and future API share payments-dashboard-compatible status ladders, pay-date helpers, and CSV headers. * fix(web): build shared package before vite dev Ensure fresh npm ci && npm run dev (and Playwright webServer) can resolve @seahaven-ap/shared dist exports that are gitignored.
