feat(logging): improve exception handling and add comprehensive logging

JobExceptionHandlingBehavior:
- Add ILogger for diagnostic output
- Change ResultText to include full exception details (ToString())
- Log JobException with warning level including ProfileId, JobName, ProcessName, BatchId
- Return default instead of re-throwing to allow graceful handling

ReCRequestExecutionBehavior:
- Convert to primary constructor pattern
- Add ILogger for request tracking
- Store RecActionResult in command for later use
- Log successful ReC requests with detailed metrics (TotalActionCount, ActionExceptionCount)
- Improve error handling and logging
