Coupons Page Showing "Coming Soon" Instead of Previously Available Coupon List

Describe the bug
The Coupons page in the admin panel (or vendor panel) is now displaying a "Coming Soon" message. Previously, this page displayed a list of active and inactive coupons. The content seems to have been removed or hidden unexpectedly, affecting access to coupon management features.

To Reproduce
Steps to reproduce the behavior:

Log in to the admin/vendor panel
Navigate to the Coupons page
Observe that instead of the coupon list, a "Coming Soon" message is displayed
Expected behavior
The page should display the list of existing coupons as it did previously, with options to create, edit, or deactivate them. The "Coming Soon" message should not appear if the feature was already available and functional.

Additional context
This may be a regression or a mistakenly pushed change. If coupon functionality is intentionally being modified or phased out, a proper notice should be shown instead of reverting to a placeholder.

No file or test is named. Start at the admin or vendor panel's Coupons page and search the frontend for the "Coming Soon" message, then trace the page entry point and its data source. Done means the existing active and inactive coupon list is visible again with create, edit, and deactivate options, and the placeholder no longer appears unexpectedly.
