Update course title

[AlexVelezLl]

Summary

• The side panel in ResourceLayout now opens by default when the screen is large enough (non-modal breakpoint), using a watcher that triggers immediately on mount.
• The page title in CourseUnitView is now shows the pre/post-test title (e.g. "Unit 2: Algebra - Pre-test") during tests, the current resource title when viewing a resource, and falls back to the course name.
• Course title is now wrapped in a <h1> tag.

This looks exactly like the expected code, but when I was reviewing in the browser, it looks like the title isn't actually truncating with the '...' the way I would expect. This might be something in the KTextTruncator? I'm not totally sure. It's also possible that it's just because it's local and i'm resizing the page, but it looks like it's covering the hamburger icon as well.

Is this something you can reproduce as well Alex, or is it just me?

Hmmm, I thought I had already fixed that in the past, in general this is a problem with our KToolbar, we could set this min-width on KDS, but that'd take time to see that this introduces no regressions, and since we will have a refactor on KToolbar anyways learningequality/kolibri-design-system#1183, I think its okay just to add this with the deep selector.

Here is the fix.

Thank you for fixing this -- I think we may have lost this behavior somewhere along the way but I'm not sure where and it wasn't intentional.
