Add setuptools dynamic version & refine tests

Add a setuptools dynamic version entry in pyproject.toml so package version is taken from dlclivegui.__version__. Also include package-data for dlclivegui.assets.

Refactor tests/gui/test_app_entrypoint.py to import cv2 at module level and skip the test module early when OpenCV is not available (removed a duplicated try/except). Tighten the assertion in test_generate_ascii_lines_crop_alpha to compare the actual generated ASCII content (lines) rather than only lengths, and clean up related comments.
