fix(@cockpit/deployment): Check if contracts deployed when connected to metamask

When connected to metamask, and “Injected Web3” is selected on the Deployment page of Cockpit, check to see if contracts have already been deployed or not.

For contracts that have not been deployed, or set to an address in the config, these should now all be re-deployable.

Supports libraries (that have bytecode with `0x73<address><bytecode>`).
