Fixed an oversight in the logic in one of the steps to update and create shifts from the timesheet approval page, which led to update or create requests being sent with the users credentials instead of the employees
Timesheet: fix UI spaces with scrolling, change ui to not show preset apply if no preset set to employee. Layout Drawer: fix display of options according to user permissions, fix highlight of menu item to match current route name. Employee list: add functionality to prevent users without user management permissions to see or edit user info and prevent seeing inactive users, add remote to shifts for preset editor, add hover effect to employee items when management mode to visually hint at clickable item.
removed modal for shift creation/update to better match current timesheet app and avoid adding superfluous user actions. Tweaked appearance of timesheet and overall theme to remove overcrowding of colors/elements
