Remarks
PURPOSE: Provides a flexible AI model wrapper for custom inference workflows where execution logic is supplied as a Python script template instead of being hardcoded in the DK11 class.
BEHAVIOR: The class stores model metadata, required Python modules, and placeholder tokens, then builds runnable script text by replacing model and image path placeholders in the template.
CONSTRAINTS: Execution depends on a valid Python environment provided by TGIS_AIPythonManager. Script generation requires matching placeholder tokens in the template text.
