IMO should be no water leaking, use paper towel to check for leaks. ( Look at top see if you see signs of joint leakage?) How old water heater are you talking about? If original the tank probably has tiny leak. Surprising there no water in drain pan? Even if pan has tiny rust leak still should be signs of water?
Another thing, you said drywall was wet? How far up the drywall? Does the water heater pipes go into that wall beside water heater at top?
