Remove Feature Flag in Multiple Extension Request Feature from Frontend and Backend

Overview:

The current implementation of the multiple extension request feature includes a feature flag that needs to be removed from both the frontend and backend. This task involves disabling the feature flag to fully deploy and integrate the functionality without any user-facing issues.

User Stories:

• As a user, I want to be able to submit multiple extension requests seamlessly.
• As a user, I expect the interface to be responsive and error-free when submitting multiple extension requests.
• As a developer, I want to ensure that the feature flag removal does not introduce any regressions in the existing codebase.
