Making icons consistent, adjusting spacing, and moving the "Leave Call"
button to be the very last, which makes more sense to me than the
"Share" button being the last. Sharing your project is still part of the
call, so in the left edge of the button strip is where, conceptually,
the option to end the call should be, I think!

This PR improves adding and working with icons by using the new
`DerivePathStr` to derive icon paths.
This means paths no longer need to be manually specified, and the
`IconName` and file name will always be consistent between icons.
This PR does not do any work to standardize icons visually, remove
unused icons, or any other such cleanup.
