Update example imports to use @/ path aliases

[Karrrthik7]

What?

Updated the i18n-routing example to replace deep relative imports with the @/ path alias.
All imports like ../../../i18n-config are now @/i18n-config. Added a local tsconfig.json to support the alias and a safe refactor helper. Changes are scoped to examples/i18n-routing only and do not modify framework code.

Why?

• Improves readability and maintainability by removing fragile "../../../" imports.
• Aligns the example with common TypeScript + Next.js conventions using path aliases.
• Makes future refactors and file moves within the example less error-prone.
• Keeps changes local to the example so framework behavior is unaffected.

How?

• Replaced deep relative imports in:
  • page.tsx
  • layout.tsx
  • locale-switcher.tsx
  • counter.tsx
    with @/ aliases.
• Added/updated tsconfig.json:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": { "@/*": ["./*"] }
  }
}
