Description:

closes #823
This pull request refactors the TimeIncrement.display method to utilize the clockLabelInMinutes function for better readability and maintainability. Additionally, it addresses an edge case noted in issue #823, where non-integer minute values were not displayed correctly. This ensures the correct display of time increments such as 1.5+5.

Changes Made:

1. Refactored TimeIncrement.display Method:

   • The display method now leverages the clockLabelInMinutes function to convert time in seconds to a more readable minute format.
   • This change simplifies the logic and ensures consistent formatting for various time values.

2. Fixed Edge Case:

   • The issue where a time of 90+5 seconds was incorrectly displayed as 1+5 instead of 1.5+5 has been resolved.

3. Added Unit Tests:

   • Created a new test file time_increment_test.dart to cover the functionality of the TimeIncrement class.
   • Tests include initialization, JSON serialization, display string formatting, estimated duration calculation, equality checks, and the clockLabelInMinutes function.

Files Modified:

• lib/src/model/common/time_increment.dart:
• test/model/common/time_increment_test.dart:

Testing:

• Verified that all unit tests pass successfully, confirming the correctness of the display method and the clockLabelInMinutes function.
