Consolidate TypeScript and @types/node versions across monorepo

- Add @types/node override (20.14.14) in root package.json to prevent
  version drift. Previously @remix-run/dev was pulling in @types/node@22
  which conflicted with the rest of the codebase expecting @types/node@20
- Add "node" to webapp tsconfig.json types array to fix Buffer and other
  Node.js type errors in local typecheck (types: ["vitest/globals"] was
  restricting automatic type inclusion)
- Update e2e fixture emit-decorator-metadata to use @types/node 20.14.14
  instead of 22.5.4

This addresses local typecheck giving false errors about Buffer etc.
while CI passes (different @types/node versions being resolved).
