Fixes#30690.
Before this, we were adding all users to subscriber list without adding
any pill. But, since we want pills to be the source of truth for adding
the subscribers, we will just add the `role:everyone` pill from now on
whenever `Add all users` is clicked.
While we can just directly call `pill_widget.appendValue` in
`stream_create_subscribers`, it's better to expose an API from
`add_subscribers_pill` and use that. This lets us control how appending
an item would work for subscriber pill in a single place.
Fixes#29825.
Clicking on remove button will not delete the row anymore. We will
add a strikethrough to the user pill and email text. `Remove` button
will change to `Add` on click to undo this action.
Re-adding a user explicitly should will not undo the soft remove on
their row. e.g If `Iago` was added as part of a group and crossed out.
Now, adding another group with Iago as part of it should not undo the
soft remove.
We maintain a seperate set of soft removed users, but we will not
remove those users from the main user list on clicking `Remove`.
That list can only be modified by actions with the input pills.
We will subtract the soft removed user ids from main user id list
when sending the request to add subscribers to the new channel.
I've not added extra puppetteer tests, since adding users was
not part of the existing tests.
The generic argument of InputPillContainer should not be
InputPillItem<…>, as InputPillContainer already uses InputPillItem
where applicable.
