refactor(send): execute prepared transaction in saga (valora-inc#5001)

### Description

Execute prepared tx directly in the send saga instead of using the
viem/saga's send payment method, which was simulating a contract call
and then executing it.

### Test plan

Manual, CI

### Related issues

- Fixes ACT-1049

### Backwards compatibility

Yes

### Network scalability

If a new NetworkId and/or Network are added in the future, the changes
in this PR will:

- [X] Continue to work without code changes, OR trigger a compilation
error (guaranteeing we find it when a new network is added)
