Fix function call ordering in dev deployment scripts

[leopoldjoy]

Both DeployDevNoNitro and DeployDevWithNitro had _registerProposer called before _deployInfrastructure and _deployTEEContracts, meaning it attempted to call setProposer on address(0) and would revert on every run.

Fix the ordering so infrastructure and TEE contracts are fully deployed before the proposer is registered:

1. _deployInfrastructure
2. _deployTEEContracts
3. _registerProposer
4. _deployAggregateVerifier

The bug was introduced in #201.
