feat(protocol): allow whitelisting proposers

[dantaik]

Besides the whitelisting support for proposers, this PR also includes the following changes:

• Move whitelisting to separate struct for easier cleanup
• Rename constants so their names starts with "K_" for readability
• Specify function/event parameter names explicitly if there are more than 2 parameters.
• "Finalize" => "Verify"

Another purpose of this PR is to enable a cleaner tokenomics PR.
