feat(contract-verifier): Auto-verify the same bytecode

[popzxc]

Depends on #3190

We need to automatically verify the contracts with the same bytecode:

• When a new contract is deployed, we should check if the verification data for this bytecode exists. If so, it shouldn't require additional verification.
• When a new contract is verified, we should check if there are other contracts with the same bytecode. If so, they should become verified.
• This should interact with partial matches: if there are differences in metadata, the contract should still be considered verified with partial match, but it should still be possible to do the "full" verification later.

⚠️ Don't treat the acceptance criteria as an implementation proposal: likely we don't actually need to scan the whole contracts table each time we deploy a contract or verify it. Most likely, we may just change the way we query verification data.
