Subject: [PATCH] chore(auth-client): replace esbuild with tsc/ts-node in
 packages/fxa-auth-client

Because:
- We want to test & develop with what we deploy.

This commit:
- Part of the esbuild -> tsc/ts-node migration (split of a6d1a55ae4, PR mozilla/fxa#20390).
- Scope: files under packages/fxa-auth-client.
