This update reverses a recent change that exposed sensitive time-off type information to all users within the time-off overview. The change was causing a security vulnerability by displaying private time off details. This fix restores the previous system where time-off colors were based on 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.
