Hi OP
First, sympathies. It sounds really difficult. On the positive side, it's really good that she's cheery and chatty in the afternoons. Can you talk to her about it in one of those phases and see what she thinks.
I have a DD who sleeps late and finds it hard to get up in the morning. DH was the same as a teen. We ask as little of her as we can in the mornings (e.g., not expected to chat about her day/sit in the kitchen with us and have breakfast). I endeavour to get her to get as ready as she can the night before, with mixed success rates!
What's she doing before bed - does she have her phone/computer etc. Can you switch off wifi when you go to bed so at least that bit of it is under control. Can you get her to agree on a winding down routine and lights off time.
I have no real idea about the hard of hearing part, I'm afraid. Presumably she won't hear an alarm clock and you have to wake her. Have you considered/tried a sunrise alarm clock (I think lumie is a common brand). Apologies if that's really basic and obvious.
The hitting you and pulling your hair obviously isn't OK and she needs to understand that.
Have you thought about just letting her take the consequences of sleeping in. If she misses the bus, is there another. What if you just let her organise herself and take the consequences (again, the hearing issue may mean that wouldn't be appropriate, I realise).
Hope some of those thoughts are helpful and you're doing OK.
