feat: initialize SvelteKit frontend with Tailwind and OpenAPI types

- SvelteKit SPA mode with adapter-static (index.html fallback)
- Tailwind CSS v4 via @tailwindcss/vite with custom color palette
- CSS custom properties for dark/light theme (dark is default)
- Epilogue variable font with preload
- openapi-typescript generates src/lib/api/schema.ts from openapi.yaml
- Friendly domain type aliases in src/lib/api/types.ts
