Also refactor mobile UI/UX for timesheet: reduced header bloat, made only shifts scrollable, added left or right swipe to travel between pay periods, showing default 'no data' message when beyond 6-month-back 1-month-forward timesheet scope.
Change timesheet UI to better fit current app model and avoid adding extra clicks and interactions to add new shifts and expenses. Also refactoring calls to backend to be more efficient and use recently-finalized OIDC implementation and integration.
