console: refactor console.flowview.mode

We now have:

console.flowview.mode           gets the current mode
console.flowview.mode.options   gets the possible options for the mode
console.flowview.mode.set       sets the flowview mode

This is quite a common pattern in our commands, to the point where we should
formalise it.

Fixes #2655
