This update reverts a recent change that exposed sensitive time-off type information to all users within the time-off overview. The change was made to improve visibility, but it created a security risk. This fix restores the original system where time-off color was determined by type, ensuring data privacy.

This commit reverts back the change done to gantt color of time-off overview to be based on time off type instead of employee, which made private information (time off type) available to everyone.
