Improve daemon console for daemons on multiple hosts

Summary:
Ref T10756. This:

- Fixes T7307. This UI is now admin-only.
- Makes the main "running daemons" table more useful for multi-host setups (show where daemons are running).
- Removes logs from the web UI: these are sometimes vaguely sensitive and shouldn't be visible. The UI tells you how to get them with `bin/phd log`.
- Minor modernization.

Test Plan:
- As a non-admin, viewed daemons (access error) and bulk jobs (worked great).
