Add seed support and update Gradio interface

Added a `seed` parameter to `generate_and_apply_maze_to_input` for deterministic maze generation. Updated Gradio interface with a `maze_seed` slider, adjusted default values for `maze_width` and `maze_opacity`, and included the `seed` parameter in the maze generation logic. Replaced `style_20250314.css` with `style_20260316.css` for updated styling.
