I don't know exactly, why your sed command fails, but Charles Duffy has a point.

I would like to introduce a more Chef way of managing configuration files.

There is a template resource, that creates a file from an .erb template adding some variables:

# template (templates/default/file.conf.erb)
key1 = value1
key2 = <%= @value2 %>

# recipe
template '/etc/conf/file.conf' do
  source 'file.conf.erb'
  variables(value2: node['value2'])  # this will set @value2 in template to node['value2']
end

If you can use template, then you should. But if you can't, for example this file can be also changed by other software, then you can use Chef::Util::FileEdit library:

How can I change a file with Chef?

In your case you will probably need:

ruby_block "Do some regex replacement" do
  block do
    fe = Chef::Util::FileEdit.new("#{node['aem_dispatcher_cookbook']['user']['home']}/.profile")
    fe.search_file_replace('umask 007', 'umask 022')
    fe.write_file

    fe = Chef::Util::FileEdit.new("#{node['aem_dispatcher_cookbook']['owner']['home']}/conf.d/author_farm.any")
    fe.search_file_replace('AUTHOR_HOST', ENV['AUTHOR_HOST'])
    fe.write_file
    [.. and similarly with other files ..]
  end
end
