Evaluate TypeScript bundler module resolution for package exports

Change the docs TypeScript configuration from moduleResolution: "node" to moduleResolution: "bundler" so TypeScript resolves package exports maps the same way the Docusaurus webpack build does.

This should allow public package subpath imports such as @temporalio-web/consent-banner/core to use the package's shipped type declarations directly, without local compatibility shims.

Scope:

• Update tsconfig.json to use moduleResolution: "bundler".
• Remove types/temporalio-web-consent-banner.d.ts if TypeScript resolves @temporalio-web/consent-banner/core directly.
• Run npx tsc --noEmit -p tsconfig.json.
• Run yarn build to confirm Docusaurus still builds with the updated resolver assumptions.
• Fix any package import errors exposed by stricter package exports handling.

Notes:
A quick static scan found no obvious unexported package deep imports. Existing package subpath imports appear to be exported by their packages, including Docusaurus client/internal entrypoints, Algolia, Chart.js, React Icons, DocSearch, and the Temporal consent banner core entrypoint.

Start with tsconfig.json and inspect types/temporalio-web-consent-banner.d.ts and the documented package subpath imports. Run npx tsc --noEmit -p tsconfig.json, then yarn build; update the resolver configuration, remove the compatibility declaration only if direct resolution works, and fix any package import errors exposed by package exports handling.
