Integrate Telcoin global styles into Vite app

[fabcrowd]

Summary

• copy the legacy Telcoin design tokens and global styles into telcoinwiki-react/src/styles and add a single global.css entry point
• load the aggregated global stylesheet from main.tsx so tokens such as .tc-card are available before React renders
• convert App.tsx to a CSS module-backed component and update vite.config.ts to use vitest/config for type-safe test settings

Testing

• npm run build
