Description

This PR fixes a division by zero error in the getActiveLogsRatio method of ClinicActivityDataService. The issue occurs when there are no logs of a specific type, causing the denominator to be zero.

Changes Made

1. Added check for zero denominator in getActiveLogsRatio
2. Added proper error handling and logging
3. Return 0 when no logs are found (denominator is zero)
4. Converted ratio to percentage for better readability

Testing

• Added handling for edge case when no logs exist
• Improved error logging for better debugging
• Returns 0 instead of throwing exception when no logs exist
