I think you are worrying needlessly. Leaving a charger connected overnight is not going to do your battery any noticeable harm at all.
Ideally, you should disconnect the charger once the battery is fully charged, but if bedtime comes first - then go to bed ! Keeping the battery on charge continuously will shorten battery life, or so the supplier of a spare battery informed me once. He also said that once the battery is charged you should run the laptop on the battery until you get the low voltage warning and then plug the charger back in but don't worry about one night.
Further, unless Captain Chicken, at #2, saw something in your images that I didn't, I don't think you have a potential battery problem. Your second image shows "Battery health: excellent."
To be fair, I wasn't exactly worried. I think it's because the last laptop I had got an extremely old battery (it was an Apple Laptop from I think 10 years ago) and how most of the items I have with batteries are hand-me-downs that suffer from overcharge or have old batteries.
I'm well aware of how batteries are now advanced enough to shut off the charging process when they are fully charged. But seeing the amount of time made me confused, and in the process, yes, worried. I came over to here to find out if there was anything remotely wrong with the battery, but I managed to fix the problem.
And yes, I do tend to charge the battery once it hits 25%, some times a little earlier. I'll try not to sweat over one night and be sure to charge only when it needs it. Thank you.
