🍂 chore: Prune Deprecated Packages From the Dependency Tree (#14483)

Removes three of the eight deprecation warnings emitted on `npm install`.

- Drop `@types/winston` from `packages/api` and `packages/data-provider`.
  The published tarball ships no type declarations at all, so `winston`'s own
  types were already being used. Declare `winston` as a devDependency instead,
  since both packages `import type { Logger } from 'winston'` and were relying
  on hoisting to resolve it.
- Drop `rollup-plugin-postcss` from `packages/client`. It is unreferenced since
  the package moved to tsdown, and pulled in `cssnano -> postcss-svgo -> svgo@2`,
  which is the only consumer of the deprecated `stable`.
- Override `test-exclude` to ^8 so `babel-plugin-istanbul` stops resolving
  `test-exclude@6`, which pins the deprecated `glob@7`.

The remaining five warnings (`ldapjs`, `whatwg-encoding`, `node-domexception`,
and workbox-build's `glob`/`source-map`) are transitive with no non-deprecated
version available upstream.
