No interests, no hobbies, no friends. You guys have kids but although she goes through the motions, you get the feeling she doesn’t really care about them. There is no affection toward you or your family and their never was. Her father dies from a car accident and your wife neither cries or grieves. You later learn she was severely abused by her parents at a very young age.
She was a distant relative and it was an arranged marriage. The first time you spoke to her was after the wedding. In your hotel room, you asked her if she would like something to drink. She replied that you could bring her whatever you wanted.
She needs to see and feel love. Her childhood must have been something horrible and she has her guard up so hopefully the man she married can show her how to be loved and feel loved.
Honestly I don't know to what extent she has been abused but I am sure she will simply recognize acts of kindness. Just being a friend to her might be a good start.

What now?
Tried talking to her about this? If so, what was the reaction like? Does she realize that her actions are a concern for people around? If her brought-up wasn't normal, you don't expect the behavior to be any normal either. The good news though is that it can be fixed. First step is talk to her. She might have real hard time trusting but you can use different tactics, being really polite at one time and a bit harsh at others (but don't start scolding, may be try emotional blackmailing) and something will definitely work which will make her discuss issues.
She does need to have a hobby. Find out the interest and may be get her enrolled in some training for that. If there are no friends, she's bound to be socially awkward but let her groom at her own pace in front of strangers. She might be too cautious in front of family (parents, inlaws, husband, kids) to even try being social.
you mean she is ‘characterless’? 
you mean husband got jannat in this world.
