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).
• Browsed bulk job pages.
• Ran a bulk job.
• Viewed daemon console.
• Viewed task detail / daemon detail / daemon list pages.
