Enatega Admin-Dashboard + Customer: Ensure Consistent Naming for "Voucher" and "Coupons"

Issue:
The terms "Voucher" and "Coupons" are used interchangeably in the system, leading to inconsistency and potential confusion for users.

Impact:

Users may not clearly understand whether "Voucher" and "Coupons" refer to the same feature or different functionalities.
Inconsistent naming can create confusion in the UI, documentation, and communication.
It may affect API responses, database fields, or reports if both terms are used inconsistently in different places.

Recommendation:

Choose a single, consistent term: either "Voucher" or "Coupon."
Update all instances of the term across the UI, API, documentation, and database schema.
Ensure consistency in user-facing messages, buttons, forms, and reports.
Communicate the change to relevant teams to maintain uniformity in future development.

Review the Admin Dashboard and Customer UI, API responses, documentation, database schema, and reports to inventory uses of “Voucher” and “Coupons.” Start by locating each term across those areas, then confirm which single term should be retained with the relevant team. Done means user-facing text, API fields, database fields, documentation, and reports use one consistent term.
