Migrated UserTable to KTable (Without Sorting)

[BabyElias]

Summary

Migrated UserTable (as seen in UserPage.vue) to KTable.
This is with reference to #12705 which involves migrating Facility>Users table from the current UserTable implementation to KTable. Sorting functionality will be introduced in the next PR; this one focuses on checking any regressions that might have been made while migrating the Facility>Users table to a KTable-based implementation.

References

#12705

Reviewer guidance

• Navigate to Facility>Users.
• This page currently has both the original table (the top table) and the new KTable implementation (the bottom table). Once it's confirmed that KTable behaves similarly in all expected ways as the original table - the previous implementation will be removed.
