feat: transfer fees to treasury

[devwckd]

Closes CHAIN-60

[linear]

CHAIN-60 send fees to treasury instead of burning

[functor-flow]

We need to refactor the logic completely so there is no burn and mint in the first place

The whole process would be:

Submit proposal / application -> goes straight to treasury (transfer)
Not accepted -> keep in treasury
Accepted -> send from treasury back to payer

so you will transfer from payer to the treasury

something like

   <pallet_balances::Pallet<T>>::transfer(payer, treasury, value)

there are a few dbgs in the code, other than that, lgtm
