feat(reporting): add billable and non-billable time tracking to member reports

- Implemented SQL logic to calculate billable and non-billable time for team members in the reporting module.
- Enhanced the reporting members table to display new time tracking metrics with appropriate headers and tooltips.
- Created a new TimeLogsCell component to visually represent billable vs non-billable time with percentage breakdowns.
- Updated localization files for English, Spanish, and Portuguese to include new terms related to time tracking.
