[Refactor] Improved logging for Controller Server

[komer3]

This PR replaces the use of klog with structured logging using the logger package in the controller server. Key changes include:

• Implement consistent logging patterns across all controller server methods
• Improve log messages for clarity and add more context where appropriate
• Remove redundant logging statements and consolidate logging information
• Utilize log levels (V(2) for method entry/exit, V(4) for detailed operations)

These changes enhance the observability of the controller server operations and make debugging easier by providing more structured and consistent log output.
