Will the battery charge using a wall charger?
No, it was not dropped, nor was it near moisture.
The last thing I did before it happened was leave it plugged in (via wall charger) with an alarm set for the morning. At that point it was working fine.
No, I usually start charging it around 40%, and leave it plugged in longer necessary (via computer cable).
Yes, it receives power via wall charger. If I have the battery in, it does the same lack of response with the slowly flashing light that I described. If I remove the battery and leave the phone plugged in via wall charger, there is no change, so it is receiving power from the wall charger.
