Improve empty states of 'Score' and 'Publish' tabs

[avvvvve]

If you haven't opened a score yet, there is no use in opening the 'Score' or 'Publish' tabs because you can't do anything in them.

A user reported this issue (video below), which suggests some confusion around what is possible to do in those tabs when no score is open.

Potential design ideas:

Disable the tabs

• Disable the 'Score' and 'Publish' tabs if no score is open

OR

Provide a quick action to open a score

• Add CTAs in the blank canvas area in those tabs, i.e. 'Open score' and 'Create new score'
• Hide any open panels (i.e. Properties/Instruments/Palettes) in the 'Score' tab

I would suggest a non-interactive message in the blank canvas area, something like this:

It seems to me that an interactive message (buttons) of "create new score" and "open score" doesn't fit in a "blank" workspace.
I remember other programs have non-interactive messages in blank workspaces, too, though I can't think of any off the top of my head...

Agreed. Maybe we can refer to Visual Studio Code.

I think I'm partial to just disabling Score/Publish if nothing is open, at least as a first fix.
