This commit adds a reset function for the subscribe widget so that
whenever someone subscribes to a stream from the dropdown, after
the subscription, the dropdown will return to its initial state
with no stream selected. Additionally, it will display a label with
the subscribe button disabled and a tooltip.
This commit adds a tippy tooltip to the subscribe button in
the user profile. We show this tooltip only when there is no
stream selected and the button is disabled. However, on any
change, we enable the button and hide the tooltip.
This commit adds a subscription widget to the user profile,
including the logic to prevent non-admin users from seeing the
subscription widget of other users. Additionally, as it is not
possible to subscribe generic bots to streams, and the user should
not be a deactivated user, we check for these conditions before
displaying the subscription widget.
To ensure that the alert for both subscribing and unsubscribing
appears on top of the subscribe widget, changed the location of
the alert to be displayed at the top.
Additionally, considering that no stream will be initially selected,
we have made the decision to disable the subscribe button. Once the
user selects a stream, we will enable the subscribe button
accordingly.
Changed the add_user_ids_to_stream function inside subscriber_api.js
to support self subscribe also, so that we don't have to duplicate the
logic in user_profile.js
Created a separate file for the subscribe widget called
user_profile_subscribe_widget.hbs.
