TL;DR: Your baby's fine. They know what they're doing. Talk to your wife about what she needs from you to survive this difficult period. Chuck your feed schedule into a closet and don't come back to it for at least a month.
We constantly have to try to find ways to wake her so she can finish eating
Unless she's underweight or not putting on weight or you're struggling with producing milk or your doctor has given you special guidance, you don't have to do this. You can try and enforce a feeding schedule for your own sanity, and there's nothing wrong with making that call, but do note that a newborn daughter doesn't know what time is, let alone what time it is.
If she was properly hungry, she wouldn't be going to sleep, she'd be on that boob till she was good and finished. If she's content and comfy, she'll pass out, secure in the knowledge that food'll be there when she wakes up. You can expect small frequent "snacks" that will slowly become longer "meals", but babies are people, sometimes they're just "snackers" for months until they're old enough that you feel comfortable to enforce a schedule.
So what is normal? Well, how long have you got? Because there’s a lot of normal. A newborn should feed a minimum of 8-12 times in 24 hours. That means some might be going every 3 hours and others will be feeding more frequently than 2 hourly. Some babies may feed every 10 minutes every hour. Some may feed for 10 minutes every 2 hours. Some may feed for 40 minutes every 2 hours. For periods in the day, a younger baby will often cluster feed and not be happy away from the breast for any longer than a few minutes at a time. This natural cluster feeding may dominate an evening.
A very common call to the National Helpline goes like this: “My baby used to sleep in the evenings and now he’s awake for 3-4 hours. The only thing that seems to settle him is the breast. I feel like I must not have enough milk as he’s on there for ages. Surely there can’t be anything there.” As the baby swaps from breast to breast, getting small quantities of very high fat content milk and decompressing at the end of a long day, they know exactly what they are doing.
And soon their patterns will change again. Some babies will start to longer intervals in the day as the months go by. But NOT all will.
It's absolutely fine and normal, especially in the first month. The main reason you might want to enforce longer feeding schedules is to protect the mother's sanity, which is really important, but the baby doesn't care about mummy's sanity, the baby is literally developmentally incapable of caring about anything other than their immediate needs.
What makes this worse, is that our baby girl has a really hard time falling asleep in her bassinet.
Yeah, she'd clearly rather sleep on Mummy. Mummy is comfortable and has food on tap. The bassinet, no matter how nice, is fundamentally "not Mummy". You can expect this attitude to continue for as long as they think they can optimistically get away with it. One viable approach to support Mummy is to have one formula bottle on stand-by so that Daddy can take his shift as the mattress of food.
Currently she is averaging around 11 or so hours of sleep per day, which seems low relative to everything that’s out there.
Eleven's potentially low, but not unusual. Also, newborns tend to sleep in little bursts, so even if you're timing it, you're probably not noticing some of the cat naps, especially as your brain will be fried from your own lack of sleep.
For ref, she is one week old.
Note that this is a tiny period of time, and her behaviour may change rapidly within the month. As long as she appears healthy, just do whatever's easiest for now. If she wants to snack constantly and pass out on Mummy, and Mummy can live with that situation, let them do that, and have Dad do all the work that requires mobility or free hands.
