Add TypeScript type definitions for API data models

[Copilot]

Define TypeScript interfaces mirroring backend API response shapes for compile-time safety across frontend code.

Files Added

• src/frontend/src/types/god.ts: Alias, God, and GodInput interfaces
• src/frontend/src/types/mythology.ts: Mythology interface
• src/frontend/src/types/index.ts: Barrel export for convenient imports

Type Definitions

export interface God {
  id: number;
  name: string;
  description: string;
  mythologyId: number;
  aliases: Alias[];
}

export interface GodInput {
  id?: number;  // Optional to support create (no id) and update (with id) flows
  name: string;
  description: string;
  mythologyId: number;
}

Types importable via import { God, Mythology } from '@/types' or relative paths.

Description

Define TypeScript interfaces that mirror the backend API response shapes. These types provide compile-time safety across all frontend code that handles API data.

Implementation Steps

1. Create src/frontend/src/types/god.ts:

   export interface Alias {
     id: number;
     godId: number;
     name: string;
   }
   
   export interface God {
     id: number;
     name: string;
     description: string;
     mythologyId: number;
     aliases: Alias[];
   }
   
   export interface GodInput {
     id?: number;
     name: string;
     description: string;
     mythologyId: number;
   }

2. Create src/frontend/src/types/mythology.ts:

   export interface Mythology {
     id: number;
     name: string;
   }

3. Optionally create src/frontend/src/types/index.ts that re-exports everything for convenient imports:

   export * from "./god";
   export * from "./mythology";

Files Created

• src/frontend/src/types/god.ts
• src/frontend/src/types/mythology.ts
• src/frontend/src/types/index.ts

Acceptance Criteria

• All interfaces match the backend API response shapes documented in Swagger.
• GodInput.id is optional (number | undefined) to support both create (no id) and update (with id) flows.
• Types are importable from @/types or ../types across the project.
