fix(cli): route PostHog networking through shared fetch (#9149)

* fix(cli): route PostHog networking through shared fetch

* remove unnecessary `as RequestInit` casts from PostHog fetch wrappers

PostHogFetchOptions is a structural subset of RequestInit, so the cast
is unnecessary. Also removes a stale comment about shared client support
in PostHogErrorProvider.
