refactor[epic-games]: migrate to GraphQL API and modularize authentication logic

Browse source 
This commit refactors epic-games.js to use the GraphQL API instead of the legacy promotions endpoint for retrieving free games. Key architectural improvements include:

- Added modular authentication module (device-auths.ts) supporting persistent device auth tokens
- Introduces cookie management module (cookie.ts) for persistent session handling
- Extracts GraphQL query structures and API endpoints into constants.ts
- Implements multiple fallback strategies: device auth login, token exchange, and fallback to standard login
- Adds support for both GraphQL and promotions-based game discovery
- Streamlines claim process with improved tracking and error handling
- Removes legacy selectors and redundant logic

Additionally, updates package.json to include TypeScript and reorganizes dependency order for better maintainability.
