replace Tailwind CLI with esbuild for admin CSS bundling. admin now uses
hand-written utility classes (admin/utilities.css), static heroicon CSS
generated by mix generate_admin_icons, plain CSS colour themes extracted
from DaisyUI plugin config, and minimal resets. rename app.css to admin.css
for clarity alongside shop.css. delete vendor/daisyui-theme.js and
vendor/heroicons.js. no Tailwind dependency remains in the project.

Add admin/components.css with custom admin-* component classes replacing
all DaisyUI component usage across admin LiveViews, auth pages, layout,
and core_components. Delete daisyui.js vendor file (246KB). Theme plugin
stays for color variables until Phase 7.
