I agree with you when you say God stated that Satan had God move against Job without cause. Satan’s cause was to destroy Job. Satan had said Job would not bless God if something bad happened to his possessions, and Satan was wrong. Job did bless God. This makes Satan’s cause unjust.
This first test does not state what God’s cause was for allowing Job’s loss of possessions. It is my opinion that Job was not saved, and his soul was heading for the pit, as we read in Job 33:24. Then he is gracious unto him, and saith, Deliver him from going down to the pit: I have found a ransom.
God’s purpose for allowing Satan to take Job’s possessions was to get Job’s attention so that he might put on God’s righteousness in place of his own righteousness.
The second test turned out far different.

The first test is without cause, and there is nothing written in chapter 2 to indicate the second test was any different. We see satan using the same tactic, except this time he raises the stakes by attacking Job's well-being (which quite literally brings Job to the brink of death by the end). So what is Job's response to this second test? Even when prompted by his own wife to curse God (as satan had again falsely predicted) Job does not curse God. What does Job do instead? "But he said unto her, Thou speakest as one of the foolish women speaketh. What? shall we receive good at the hand of God, and shall we not receive evil?" Job's attitude is one of acceptance. He willingly and humbly accepts the evil that has come upon him and refuses to curse God.
What follows is Job being accused by his friends for having sinned to incur this punishment and Job (rightly) arguing that it's not because he had sinned. He has to go to great lengths to explain himself because his friends refuse to believe him. Job is also consistently crying out to God wondering himself why this has happened to him with the aim of having his relationship with God restored. Job is satisfied at the end when God appears to him and does this very thing.
