migrate accent colours from HSL to oklch, inject theme into admin

Browse Source 
Phase 1: Replace hex_to_hsl with hex_to_oklch in CSSGenerator, output
--t-accent-l/c/h instead of --t-accent-h/s/l. All 46 HSL accent
references across theme-semantic.css, theme-layer2-attributes.css, and
shop/components.css replaced with oklch/color-mix equivalents. Dead
style*= attribute selectors for button variants replaced with proper
class-based selectors. Added color-scheme: light/dark to mood output.

Phase 2: Add LoadTheme plug to admin pipeline, extend AdminLayoutHook
with theme_settings and generated_css assigns, add font preloads and
generated CSS injection to admin_root.html.heex. No visual changes to
admin yet — .themed wrapper added in next phase.
