Refresh access token

Exchange an existing access token for a new one using the embedded refresh token ID. This endpoint implements:

• Token rotation (old refresh token is invalidated)
• Rate limiting (1ms minimum interval per refresh token)
• Automatic cleanup of expired tokens
• Security validation of token chains
