Does "all" mean "fully" here? What's the purpose of using "all" here?

You are correct! "All" in this sentence does mean fully. In this sentence, "all" is defined as the whole amount of something. Bellatrix Lestrange is telling everyone that Harry's face is back to its original form; that the whole amount of his face is normal again. Ex: Look at you all dressed up. Ex: She's all excited about going to the zoo today.
