feat: add version info in nav and Status screen, tighten nav accordingly

[jessicaschilling]

Closes #1650.
Closes #1649.

This PR ...

• Adds WebUI version number (linked to appropriate release page on GitHub) on both the nav (at widths wide enough for nav to appear at page left) and the Status screen
• Tightens left-nav formatting to improve display for smaller 16x9 format screens (as identified in The webUI should display the webui version #1649 (comment)), primarily to preserve display of version/revision/repo/bug-report links at nav bottom for 640+ high windows

Big thanks to @bertrandfalguiere for raising these issues and PRing an initial fix!

@bertrandfalguiere, do you mind testing this on your setup to see if this takes care of your height issue? This should also enable you to see #1651 in action. Thanks!

[bertrandfalguiere]

It works for me! You can merge it :)

@lidel and @rafaelramalho19 -- do you mind a quick look when you get the chance?
Hang on - actually going to include changes from #1651 here for ease of review.

OK ... @lidel and @rafaelramalho19, ready for review at your leisure. Thank you!

Having this on status is 👌, but see nit below

@lidel - Updated to just "UI". Screenshot updated in original comment at the top of this issue, but here too to avoid repetitive stress injury from scrolling:
