ui: administration: set icons for tabs

orient on PVE, the ones for Updates, ServerStatus, should by
self-explanatory.

Services is in PVE named "System", but reusing that cogs icon makes
similar sense here too, and seems in line with search result of a
"service icons" query.

Syslog is the same as our general log icon, but as we also use this
normally for worker task logs and that is present here too, I
changed the worker task log icon to the alternative list, which
resembles a task view window - so IMO even better than before.

Sync that change also into the always present tasks button at the top
right.
