`get-balance-stx` for ccd002-treasury only returns unlocked balance

[whoabuddy]

The current endpoint for get-balance-stx returns the unlocked balance, e.g.

https://protocol.citycoins.co/api/ccd002-treasury/get-balance-stx?contractName=ccd002-treasury-mia-mining-v2

Returns:

155844000

Which matches the unlocked balance and doesn't indicate anything about the 10.2M STX locked.

This comes from stx-get-balance in the treasury contract, so we may need to switch to calling the Hiro API.
