Add glass UI with backdrop blur and fix primary button colors

Apply glassmorphism to sidebar, cards, tables, modals, dropdowns,
and dialogs with semi-transparent backgrounds, backdrop-blur, and
white/15 borders. Add subtle gradient body background for the blur
to work against. Add dedicated btn-primary color tokens so primary
buttons stay bold in dark mode instead of using the brightened text
palette. Use shadow-sm to avoid heavy halos in light mode.
