Variable for storing the dropdown widget is now
declared in stream_settings_components and this
commit also adds some helper functions to get
and set the filter value.
This is a preparatory commit to avoid import
cycles in further commits for fixing live
update when channels are archived.
There is no need to store the archived status filter value in a
variable, instead value can just be derived by calling "value"
function on DropdownWidget.
This is a preparatory refactor for further commits which will fix
live-update behavior when archiving channels.
We are using `can_add_subscribers_group` instead of
`invite_to_stream_policy` to check whether a user can subscribe other
users.
We've removed `invite_to_stream_policy` from the frontend wherever
applicable.
This commit replaces the spectrum color picker used in the stream
popover and stream settings with a custom color picker popover, which
contains a grid of predefined color swatches and a custom color option.
The custom color option uses the HTML5 <input type="color"> which shows
the native browser color picker UI.
Fixes#14961.
