Bettas are labyrinth organ breathers.. they don't breathe like other fish.. they breathe the air we do.. so AQ salt won't help them breathe. It helps promote gill health, but they don't use them like other fish.
Here is what AQ salt does for a freshwater betta:
Dehydrates them - leads to kidney damage/failure.
The fish/bacteria/parasites (that they always have on them) become resistant to the benefits of the salt, making it so if they do get ich or fin rot, etc.. the salt will be pretty much useless and you will have to use harsh chemicals which can just as easily harm/kill the fish as what the ailment the fish has will do. So being exposed to the salt all the time will make the healing properties useless.
Some freshwater fish can live in slightly salty waters.. some freshwater fish can live for a very short time in salty waters.. this is where the betta lies.. normally 10-14 days is the max you want them exposed to the salt.
I don't think there is anything that "calms" a fish down like that to be honest.. a fish who is comfortable in their environment will be calm. If anything, Stress Coat would be used to help "calm" them.
