[athena poc] support deploying templates

[poszu]

Added support for deploying transactions. The singlesig wallet contract account can deploy a new contract and the principal pays the fee.

💡 It's impossible to spawn the new contract because the transaction doesn't have a template address. A follow-up PR will add support for spawning (and calling) deployed contracts.
ℹ️ this change is compatible with the existing devnet-athena-10
