Move CSS and JS from Python strings to Jinja templates

Extract the CSS and JavaScript code from __init__.py into proper
template files:
- templates/styles.css: All CSS styles
- templates/scripts.js: Copy button WebComponent and other JS

Add get_css() and get_js() functions to load and render these
templates, replacing the CSS and JS Python string constants.

This improves code organization by keeping frontend assets in
separate files that can be edited independently.
