Use modern UI elements to show daemons in Daemons

Summary:
Ref T3557. Slightly improves display of daemons:

• Makes status more clear (through colors, explanatory text, icons, and explicit descriptions instead of symbols).
• Particularly, the "wait" status is now communicated as a normal status ("waiting a moment...") with a calm blue color.
• Uses modern responsive elements.
