[Self-hosted] 'Explore review' still accessible in admin panel when FLUXER_DISCOVERY_ENABLED is disabled

Reproduction steps

Check if FLUXER_DISCOVERY_ENABLED is set to false - rexctl config get FLUXER_DISCOVERY_ENABLED
If not, set it to false - rexctl config set FLUXER_DISCOVERY_ENABLED false
Go to your instance's admin panel - Instance domain + /admin in the browser
Sign in with an account with admin access
In the sidebar, under Moderation, Explore review is still accessible.

Expected behaviour

Either a message that shows that Discovery is disabled on this instance when accessing /admin/discovery directly or through Explore review in the sidebar or that Explore review doesn't appear in the sidebar at all.

Actual behaviour

Explore review appears and is accessible from the sidebar or from /admin/discovery directly even though no communities can apply to it since the Explore option in a community's settings doesn't appear while FLUXER_DISCOVERY_ENABLED is disabled.
