Let's go through what we got done in Milestone M31 (Feb 24 - Mar 9)

- Fixed all the issues reported by `active_record_doctor`: Added a few useful indices, removed unused indices, added validations at the DB level, and at the model level. Added a data migration to migrate all blocks with a duplicate identifier in the DB.

- Fixed all the vulnerabilities during `yarn audit`.

- Fixed all the `brakeman` warnings.

- Added a default value for button nodes to handle empty edge-case.
