[Gen AI tools V2] Configuration helpers

[Linux0Hat]

This pull request introduces a new dynamic form-based configuration generator using the textual library. The changes include adding a dependency for textual and implementing a new Python script to create a multi-page form interface for generating configuration files.

Dependency Addition:

• Added textual library (version ^3.5.0) as a new dependency in pyproject.toml to support the creation of terminal-based user interfaces.

New Feature Implementation:

• Created a new script, gen_config_file.py, which defines a GenConfigApp class using the textual library. This class provides a multi-page dynamic form interface for generating configuration files in JSON format. Key features include:
  • A structured configuration form with sections for bot settings, embedding model settings, vector store settings, and additional parameters. The script can handle the configuration if she is changed.
  • Navigation buttons (Previous, Next, Write to JSON) to move between pages and save the configuration.
  • Dynamic widget generation based on the configuration schema, supporting text inputs, checkboxes, and integer fields.
