OAuth token request fails when used inside Gin middleware with context cancellation

Description
When using the SDK inside a Gin middleware, token creation fails if the request context is cancelled early.

Code snippet

r := gin.Default()

r.Use(func(c *gin.Context) {
    oauthClient := client.NewOauthClient(user, apiKey, true)
    token, err := oauthClient.CreateToken(c.Request.Context(), []string{"scope"}, 3600)
    if err != nil {
        log.Println("token error:", err)
    }
    c.Next()
})

Observed behavior
context canceled error returned intermittently.

Expected behavior
Token generation should complete even if the HTTP request lifecycle ends.
