[Feature] Allow higher API rate limits per organization

Description of Feature

Allow the API’s current 60 requests-per-minute limit to be increased for organizations with higher-volume production use cases.

Customer use case

Our test suite retries on 429 responses, but this limit also affects production.

We’re a Shopify experimentation app serving hundreds of merchants, and creating, launching, pausing, or concluding experiments triggers real-time API updates.

A shared limit of 60 requests per minute restricts how quickly we can process those actions across all merchants. Retries help recover from throttling, but they don’t increase capacity—they delay customer updates.

Please do submit the feature request for a raisable per-organization limit.
