feat(project-finance): implement time formatting utilities and update task time handling

- Added utility functions to format time in hours, minutes, and seconds, and to parse time strings back to seconds.
- Updated the project finance controller to use seconds for estimated time and total time logged, improving accuracy in calculations.
- Modified frontend components to reflect changes in time handling, ensuring consistent display of time in both seconds and formatted strings.
- Adjusted Redux slice and types to accommodate new time formats, enhancing data integrity across the application.
