## Goal
Add optional GraphQL API alongside REST API for flexible data querying.

## Description
This story implements a GraphQL API using gqlgen that provides an alternative to REST endpoints with flexible querying capabilities.

## Deliverables

### 1. GraphQL Schema
- Install `github.com/99designs/gqlgen`

  - Subscriptions (optional)

### 2. GraphQL Resolvers
- Implement resolvers:
  - Use existing services
  - Add authorization checks
  - Error handling

### 3. GraphQL Endpoint

- GraphQL playground: `GET /graphql` (development)
- Integration with authentication

## Acceptance Criteria
- [ ] GraphQL schema is defined
- [ ] Resolvers work correctly
- [ ] Authorization is enforced
- [ ] GraphQL endpoint works
- [ ] GraphQL playground works (dev)
