Update ConfigurationAsCode category and exception handling

[somiljain2006]

This PR updates the Configuration as Code management link and improves related error handling

Changes included:

• Category Update: Replaced the legacy getCategoryName() string method with the modern getCategory() API
• Exception Handling: Replaced generic TODO comments in doReplace() with thrown ConfiguratorExceptions.
• Cleaned up View Export: Removed the hacky dummy ManagementLink object in doViewExport(). The exported YAML is now passed securely as a standard request attribute to viewExport.jelly.
• Added Debug Logging: Added FINE level logging when skipping non-YAML bundled resources.
