Add logic for dynamic data_source registering

[spompea-cfa]

Add logic to dynamically register new data_source names on the fly

[Copilot]

Pull Request Overview

This PR adds dynamic data source registration functionality to handle unknown data sources encountered during message processing. Instead of failing when an unknown data source is encountered, the system now automatically registers it and retries the operation.

• Added automatic data source registration when SzUnknownDataSourceError occurs
• Enhanced error handling with message visibility restoration for failed operations
• Updated documentation and configuration to reflect the new dynamic capabilities
