Fix top bar animating on every page transition.

This fixes the top bar animating on every page transition by moving it out of InnerView, and instead making AdvisorView a wrapper component. This way, when the page transitions, AdvisorView doesn't unmount (only its child view swaps out).

This also fixes a couple of small bugs and/or style issues.

Test Plan: Login, change views, verify it works and the top bar doesn't animate repeatedly.
