fix: HTR token seed migration

[luislhl]

Motivation

We were getting an error when running the seeds:

> yarn dlx sequelize-cli db:seed:all


Sequelize CLI [Node: 22.14.0, CLI: 6.6.5, ORM: 6.37.2]

Loaded configuration file "db/config.js".
Using environment "production".
== 20250416132150-add-htr-token: migrating =======

ERROR: Validation error

Acceptance Criteria

• The seed migration that adds the HTR token should correctly set its version field.
• The seed migration should run without errors on a clean DB.

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
• Make sure either the unit tests and/or the QA tests are capable of testing the new features
• Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
