When Sentry init runs but is disabled (local dev / CI), log a debug
message so developers can see Sentry *would* send in production.
Also explicitly set replaysSessionSampleRate/replaysOnErrorSampleRate
to 0 in the client and mobile configs. Replay integration isn't
installed, so this is documentation — it prevents future accidental
enablement if an integration is ever added.
