Fleet should show queries as denylisted on the host details page

[lucasmrod]

Problem

A prospect wasn't getting results for scheduled queries and we didn't know why (#23465).
We found out during troubleshooting (on the device) that one of the scheduled queries was denylisted and was causing osquery to crash and not send results (watchdog was also turned off).

Potential solutions

Fleet currently has a denylisted field in its DB and we are currently not using it.

Fleet should surface on the host details page when a scheduled query is denylisted, something like this:

PS: So we just need a few code changes on backend and frontend, but no migration is needed.
