Bug: The FCE kill switch is incomplete. FCEs can still be enabled on the /saved and /schedules pages via the ShowFilter component, bypassing the intended restriction.
_{Severity: HIGH}

Suggested Fix

To ensure the kill switch is comprehensive, the savedShowFCEs reducer in user.ts should also be hardcoded to return false. This will prevent the ShowFilter component from enabling FCEs on the /saved and /schedules pages.

Potential issue: The emergency kill switch for FCEs is incomplete. The pull request
hardcodes the `showFCEs` state to `false`, which disables the feature on the main course
search page. However, a separate state, `savedShowFCEs`, is used for the `/saved` and
`/schedules` pages. This state and its corresponding reducer were not modified.
Consequently, a signed-in user can navigate to their saved courses or schedules, use the
`ShowFilter` component to toggle FCEs on, and successfully view FCE data, bypassing the
intended kill switch.
