Refactor: Move I18nContextValue type definition to central types directory #143

Currently, the I18nContextValue type is defined directly within language-provider.tsx. To improve maintainability and follow our project's architectural pattern of separating logic from type definitions, we should move this to a dedicated types file.

Tasks

• Create types/i18n.ts.
• Move the following type definition from language-provider.ts to the new location:

export type I18nContextValue = {
  locale: Locale;
  setLocale: (l: Locale) => void;
  t: (key: string, params?: Record<string, string | number>) => string;
  dir: "ltr" | "rtl";
  locales: { value: Locale; label: string }[];
  ready: boolean;
};

• Export the type from the new file.
• Update the import statement in language-provider.ts and any other components consuming this type.
• Make sure the app is running without problems.

Files Involved

• Source: components/language-provider.tsx (verify path)
• Destination: types/i18n.ts
