[EC-892] Hide Secrets Manager (#4347)

* [EC-892] Hide Secrets Manager

Set the secretsManager flag to false outside of dev to deactivate it in all other environments

* linting

* set base to false for maximum safety

this gets rid of having to set it in selfhosted and cloud, but i feel safer with a belt and suspenders; don't want someone setting it true in base without thinking and the feature popping up in prod before we're ready.
