docs(token-source): fix stale TokenSource:: factory references, scrub sandbox id

These belong to the base token-source work rather than the caching layer:
README and doc links updated for the free-function factories, the README
example fixed to the current endpoint() signature, a stale camelCase-alias
comment removed, and the real sandbox id scrubbed from the example.
