Check with IM what's needed for launching hCaptcha jobs funded with stablecoins

**Description**
As of now we technically can launch hCaptcha jobs funded with stablecoins. However, on Human App we rely on a couple support endpoints which operate with HMT (daily hmt spend, user stats). We use these endpoints to determine when to close the pool.

Need to check with IM how much time it will take for them to rework these endpoints so they could work with USDT/USDC rather than HMT.
