fix: Improve automation stop functionality and add debug logging

Stop API improvements:
- Added comprehensive debug logging for stop process
- Changed session status from INACTIVE to STOPPED for clarity
- Better error tracking and result reporting

Automation service improvements:
- Added isRunning check at start of runAutomationCycle to prevent zombie cycles
- Enhanced stop method with better logging and state reset
- Proper config cleanup after database update to prevent residual processes
- More robust interval clearing and state management

These changes should fix the issue where automation appears stopped
but continues running in background.
