Subject: [PATCH] feat(reporting): add utility methods for date and time
 calculations in ReportingMembersController

- Introduced methods to calculate percentage, convert time formats, and determine date-related metrics such as days left, overdue status, and if a date is today.
- Updated existing logic in getSingleMemberProjects to utilize the new utility methods for improved clarity and maintainability.
