**What** - Changes all forms to only submit on Cmd/Ctrl + Enter instead of just Enter. - Cleans up the position of submit/cancel buttons in many FocusModals that still had them in the header. - Fixes responsiveness of multiple forms - Removes the SplitView component, and replaces its usages with StackedDrawer/Modal to align the UX across the project. Resolves CC-103, CC-535
