Enabler UI Enhancements

Initial changes to the layout. Nothing sexy yet, just improved usability.

- Condensed the top status section to take up less space.
- Split the remaining space between the Data Sources and Data Sinks so that both are always visible. This solves the issue where Data Sources would take up the entire screen on small devices, making it impossible to scroll to the Data Sinks section.
- Added a specific landscape layout as the above problem became exacerbated when small screens are rotated to landscape mode.
- Removed "Recording Status" from the main layout.
