feat: add Hono API with JWT authentication

- Implement REST API using Hono framework with token-based auth
- Add JWT middleware for scope-based access control
- Create version endpoints: launcher, downloader, patches, server
- Add account lookup endpoints (by UUID or username)
- Fetch server software with signed URLs and full version data
- Add token signing utility script for testing
- Support configurable account UUID for game session creation
- Integrate API server with existing module system
