feat(protocol): disable contracts as msg.sender

[dantaik]

I'm being cautious here as many hacks are done by creating a msg-sending contract to interact with the target contract.

This PR enforce all msg.senders for proposeBlock, proveBlock, and verifyBlocks must be EOA, but doesn't prevent prover address to be contracts to receive rewards.
