fix: delete button missing after searching for a user (#4315)

When searching for a user, the projected DBInbound only contains the
matching clients, so isRemovable evaluated to alse (since a single
match made clients.value.length === 1), hiding the Delete button.

Pass the original total client count from the parent's clientCount
prop and use it in the isRemovable check instead of the projected
clients array length.
