I wouldn't be constantly threatening her and escalating the threats - where does it stop?
Also, I wouldn't try to physically force her to go anywhere / do anything - she isn't 3 years old, if you are grappling with an 8-year old you've already lost. Again, where does it stop when she continues to resist?
I think, @yesyeah, you need to find your anger, find your voice and make a plan. It's going to get rough and you need to be prepared going into it. The next time she speaks to you that way you very firmly, and very seriously tell her how DARE she speaks to you like that. You need to show her you are angry and you mean it. It is NOT OK to speak to you that way, you are not her servant and she can't speak like that to people she loves. Tell her that her things need to be out of the hallway and put away properly and you won't ask her again.
Then, if she storms off, disengage. Grey rock her. She feels powerful when she combats everything you say/calls you names so remove all and any attention or it. Everything goes off - WiFi, TV, devices removed, treat food, toys etc effectively removed if at all possible. Don't narrate it, just do it. One, short, factual explanation if she asks, no more. Do not get into a back and forth, do not get into accusations and defence. Cook dinner, continue your evening, no need to stomp about angrily. You call everyone for dinner, if she doesn't appear you say nothing - eat, chat with your children, clear away. Bedtime arrives, you do the routine, if she fails to respond you continue on, go to bed yourself if it comes to it. Do not ignore HER, that's very important - don't withdraw your affection as punishment, but you're simply cordial and not engaging with any of the behaviour.
If her things are still in the hallway, at bedtime they go in the bin. And I mean it. If you think she'll get them out of the bin then take them out of the house altogether. When she has no shoes/coat for school, this is her problem to face. Do not engage with any anger, simply grey rock it. Tell her she can spend her money to buy more. Disengage entirely with the negative behaviour.
You need to buckle up. This most likely will not be solved overnight, you need to show her waiting it out won't work. You and DH will need to work as a team and might even have to take time off work if she refuses to go to school or leave the house. That's not a threat you can allow her to win this with. If playdates get cancelled, they get factually and calmly cancelled in her earshot. Clubs are simply not attended - don't comment, just don't go- she stays behind on trips. Treats at school stop if there are any. Fighting fire with fire doesn't work - fighting fire with calm, in-control but passive rock and the fire has nothing to rage against.
Slowly, she can earn things back. For consistent, genuine respectful behaviour. Engage in discussion if she comes to you, reiterate the unacceptableness of her behaviour, don't shame, accuse or go over and over her shortcomings just keep the narrative short and factual. Don't give in the first time she says sorry, it's an empty gesture. Take her to get more shoes if she asks (politely) - and use her money just like you said.
Continue to show her warmth and affection when she comes for it, this isn't silent treatment and she is a child, she needs to feel loved always. But none, absolutely none, of the rude behaviour is acknowledged or accepted and nothing happens with regards to the consequences until she makes the choice to behave appropriately. Do not made a song and dance about it when she does, I probably wouldn't praise her overly during this period - it can feel like a gloat when someone is having to humble themselves already. Simply serve her dinner as normal if she comes when she's called, treat her like everyone at the table, get her more shoes and use her money, tuck her in if she's ready for bed when it's bedtime. Slowly, she will correct her behaviour and you can loosen the strings.
