- Replace deprecated methods on client
- Fix broken dropdowns due to select kit 2 upgrade
- Graceful error handling when Stripe keys are not configured but plugin enabled
* REFACTOR: Use api to add subscribe link
* FIX: I18n subscribe link
* REFACTOR: Use models to store some data

generated on Discourse. Subscription data storage is limited to the
external identifiers Stripe generates so we can interact with the API.
* DEV: Test/linting fixes/rake task
