chore: initial Vector 2.0 monorepo

Ground-up TypeScript rewrite of the Vector hardware parts inventory
system. Ships the full roadmap (Phases 0-8) in one initial commit:

- pnpm + Turbo monorepo: apps/{api,web,e2e}, packages/{db,shared,ui,config}
- Express 5 + Prisma 5 + zod validation + JWT w/ refresh-token rotation
- React 19 + Vite + shadcn/ui + TanStack Query/Table + nuqs URL state
- Repair/RMA, tags, bulk ops, saved views, CSV audit export
- Analytics dashboard on Recharts + EOL tracking
- Signed webhook subscriptions (HMAC-SHA256) with in-process emitter
- Vitest unit tests (shared schemas, api services/helpers) + Playwright skeleton
- Gitea Actions CI (lint, typecheck, test+coverage, build) + Renovate

Deferred follow-ups: Postgres cutover (data-migration script ready),
BullMQ worker for webhook delivery, @react-pdf PDF export, CSV import wizard.
