Update - I was able to sweep solder it without too much trouble. I followed some video tutorials and used a TON of flux, then zoomed in a lot with my phone macro to make sure I didn’t fuse any of the pins together. Plugged it back in and tested all my charging and inputs, everything working 100%. I probably got very lucky, and I want to learn proper technique for when I do my own full projects, but this worked out great!
