feat(ui): migrate to shadcn/ui component framework

This commit introduces shadcn/ui as the base component framework for the
application, providing a modern design system with built-in dark mode support.

## Core Infrastructure
- Add cn() utility function for className merging
- Add useThemeStore for theme state management (light/dark/system)
- Add ThemeProvider component for app-wide theme context
- Add ThemeSwitcher component for user theme selection
- Add shadcn CSS variables for theming in main.css

## shadcn Components Added
- button, dialog, toast, dropdown-menu, select, tabs
- label, separator, alert-dialog, input, card
- table, scroll-area, tooltip, progress, slot

## Existing Components Updated (API Compatible)
- Button: now uses shadcn button internally
- Modal: now uses shadcn dialog internally
- Toast: enhanced with dark mode support

## Dependencies Added
- @radix-ui/*: UI primitives for accessibility
- class-variance-authority: variant management
- framer-motion: animations
- clsx, tailwind-merge: className utilities

All existing component APIs are maintained for backward compatibility.
