hotfix atm premium

[talvasconcelos]

• ATM premium wasn't stored in the DB
• Value asked in the input is now in percentage (ex: 1, 3.5, etc...)

Test Steps:

• create or edit a tpos that allows ATM withdraw and set a premium percentage, for testing purposes make that a high value like 20%
• make the withdraw, check the exchange rate, it should be ~20% less than actual exchange rate (you should get less sats than doing it with the actual rate)

Actual Result:

• atm premium setting wasn't added to DB
• atm premium was always 0%, so the real exchange rate was used

Expected Result:

• the premium value should show on the tpos table
• the withdraw should account the premium and adjust the amount of sats to withdraw
