Add ServiceManager support to Payment Contract

[ethanfrey]

Swap out the "admin" controller for validating a WAVS message with a service manager contract

• Make owner an enum, so it can either be admin for local tests, or WAVS for real deploy
• Update deploy scripts to add service manager
• Provide some basic tests using service manager and actual wavs message (can be 1 or 3 operators, mainly that we parse the types)

@dakom can you link where to find the service manager contract and service handler interface for CosmWasm?

This needs #9 for the types to use to parse WAVS messages

Good start. We also need example of:

• How to call ServiceManager to validate the signatures
• How to parse payload using the types from the components

[dakom]

• how to call service manager: https://github.com/Lay3rLabs/WAVS/blob/3d78d06e9f7748db50b983833ecea32b4ccbc20b/examples/contracts/cosmwasm/mock/service-handler/src/entry.rs#L55

parse payload is totally up to us, can be bincode for example
