feat: add skip verification setting

[glevco]

Motivation

We have a single OCB on testnet-hotel that breaks the new OCB restrictions introduced in #1347. This PR adds a setting to bypass verification so we can update the full nodes without resetting the network. This is the skipped OCB: https://explorer.hotel.testnet.hathor.network/blueprint/detail/00000000af8c95ca9aabf5fd90ac44bd4f16d182618c357b301370ad0430c4a3

Acceptance Criteria

• Add new SKIP_VERIFICATION settings.
• Configure SKIP_VERIFICATION on testnet-hotel.

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
