This commit adds code to live update the membership status text
when a user is added or removed from a group that is subgroup
of the group opened in the right panel of groups UI.
id_field_name was being used only to set the initial dummy
values for realm settings. We can directly add "_id" to the
setting name instead of having an extra id_field_name field.
As we now allow anonymous groups and settings can be set to any
set of users, there is no benefit in not allowing a setting to
be set to "Owners" group.
If the user is not a direct member, but a member via a subgroup, we will
show the list of subgroups beloging to that group which the current user
is a direct member of in a tooltip. The cursor on the checkmark will be
default in this case instead of a pointer.
In `Group settings` -> `Your groups` and `User Profile Popover` -> `User
groups`, we only listed groups that a user was a direct member of. Now,
we will also list groups that a user is not a direct member of, but
associated via a subgroup.
Fixes#32486.
