Misc UI fixes (#1873)

Summary:
Continue with cleanup of Network plugin mock screens.  This mostly consists of replacing FlexColumn, FlexRow and FlexBox with equivalent Sandy components.

Here is the new screen:

- replace text buttons with Button
- add NUX info to "Copy Highlighted Calls" button
- add message when no calls have been highlighted
- in routes list remove padding on line items
