🔐 PRO Authentication

PRO endpoints require authentication via API Key in the header:

X-API-Key: lion_pro_xxxxxxxxxxxxxxxx

To generate an API Key, you need to:

1. Login as a PRO user using JWT (endpoint /api/auth/signin)

2. Generate an API Key using the endpoint /api/auth/generate-api-key

3. Use the generated API Key in all PRO requests
