Make these changes to scheduleview.vue and give me entire code:
1. In the event bars, ensure all text, including the in office and wfh, are black color when against yellow background. Make it easier to see.
2. Make the calendar scale accordingly, it can extend fully down, no need to make it scrollable. Hwoever, ensure it still fits 100% on the screen and no overflow.
