node tasks: add action column with button to view task

This is primarily aimed to make it more discoverable that one can open
tasks directly, instead of selecting and clicking the view button at the
top.

The chevron-right icon was chosen, to be more in alignmend with other
places where we use it. For now, mainly PBS.
