Update ytsage/gui/ytsage_stylesheet.py to add explicit padding for various QPushButton:pressed rules (and QPushButton:checked:pressed) across multiple style blocks. These changes unify the visual spacing and touch feedback when buttons are pressed, ensuring consistent pressed-state layout and appearance.
Moved all files from src/gui/ to ytsage/gui/ and updated import statements to use relative imports within the new package structure. This improves modularity and prepares the codebase for distribution as a proper Python package.
