Fix AppBar padding and alignment issues (#1482)

AppBar was missing a start padding that caused it to extend to the edge
of the screen on Compact size classes.

Updated the SearchBar component usage away from the deprecated method
version as an internal usage of Modifier.fillMaxWidth in the deprecated
method was now causing the AppBar to always fill max width on all Window
Size Classes (vs the intended end-aligned smaller version in
non-Compact)
