[Bug] Newly added provider not reflected in allowed provider list for Forge key

[lingtonglu]

Description

When a new provider is added to an existing Forge key, the allowed provider list does not update properly. As a result, models from the newly added provider are not included in the response from the List Models API.

It might have something to do with the underlying cache mechanism

Steps to Reproduce

1. Call the List Models API using a Forge key that has one or more providers configured.

2. Add a new provider to that Forge key.

3. Call the List Models API again using the same key.

Expected Result

Models from the newly added provider should be included in the response.

Actual Result

Models from the new provider do not appear in the API response.
