Transform Dispatcher Contract to be upgradeable proxy

Transform the dispatcher contract to use a proxy to make it easier to handle deployments

I think UUPS makes the most sense for the proxy pattern to use, as it is relatively simple and pretty flexible . What's interesting about this pattern is that we can have upgradeability for the first few iterations, and then perhaps once we've decided on a stable version we could also disable upgradeability as well for more decentralization (not saying we should necessarily head in this direction but wanted to note that it is possible)
