jamey a78a1db847 fix admin font loading and theme CSS cache miss bug
add system font stack to admin reset CSS so setup/admin pages render
sans-serif on all devices instead of falling through to browser default.
pass path_resolver to CSSGenerator.generate on cache miss paths so
font URLs resolve to digested paths in production.

defmodule BerrypodWeb.Plugs.LoadTheme do
@moduledoc """
Plug that loads theme settings and generated CSS for public shop pages.
This plug:
1. Checks the ETS cache for pre-generated CSS
2. Falls back to generating CSS from theme settings on cache miss
3. Assigns both `theme_settings` and `generated_css` to the connection
The generated CSS contains only the active theme values (not all variants),
making it much smaller than the full theme-layer2-attributes.css file used
by the theme editor for live preview switching.
