Title:
Fix tgcf-web command compatibility with Python 3.12

Description:
This patch addresses an issue with the tgcf-web command when running on Python 3.12.

Problem:
The tgcf-web command previously used importlib.resources.path() with an empty string to obtain the package directory, which caused a StopIteration error in Python 3.12. Subsequent attempts to convert the returned object with os.fspath() or to use wu.__file__ failed because wu.__file__ returned None.

Implemented Solution:

• The code has been modified to obtain the package directory based on the run.py file itself using the __file__ attribute.
• The problematic line has been replaced with:

  package_dir = os.path.dirname(os.path.abspath(__file__))

  This ensures that the correct path is obtained without relying on APIs that behave differently in Python 3.12.

Testing:
After the change, the tgcf-web command executed successfully, launching the Streamlit server without any errors.
