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.
For spectators, the chunk of page_params that originates from
do_events_register isn’t assigned until ui_init.js. That means the
TypeScript type of page_params is mostly a lie during module load
time: reading a parameter too early silently results in undefined
rather than the declared type, with unpredictable results later on.
We want to make such an early read into an immediate runtime error,
for both users and spectators consistently, and pave the way for
runtime validation of the page_params type. As a first step, split
out the subset of fields that pertain to the current user.

page_params.narrow may be undefined, page_params.server_sentry_dsn may
be null but not undefined, and page_params.user_id may be 0 (for
spectators) but not undefined.

While `user_id` from `page_params` is marked as `number | undefined`,
when fuctions in this file are called, `page_params.user_id` will
never be undefined. Verifying from all of callers of
`initialize_with_current_user`, this is because when user is able
to create and initialize a stream, this user is authenticated and
thus a `user_id` is always available. Therefore, adding an assertion
when undefined user id is detected to handle a confirmed error.
