Fix: Indent production in industry window and resolve button issues. (#10184)

Industry production used to be indented, although a different amount than
the industry accepts list. This is now added back, with the standard indent
width.

Additionally the cheat-mode production modifier buttons now support RTL and
the list height now takes account of the button height.
