hscontrol/templates: refactor to use CSS classes and embedded files

Refactor template system to use go:embed for external assets and
CSS classes for styling instead of inline styles:

- general.go: Add go:embed directives for style.css and headscale.svg,
  replace inline styles with CSS classes (H1, H2, H3, P, etc.),
  add mdTypesetBody wrapper with Material for MkDocs styling

- apple.go, oidc_callback.go, register_web.go, windows.go:
  Update to use new CSS-based helper functions (H1, H2, P, etc.)
  and mdTypesetBody for consistent layout

This separates content from presentation, making templates easier
to maintain and update. All styling is now centralized in style.css
with Material for MkDocs design system.
