Unify Iron Textures

Right now there are 3 highly distinct categories of iron texturs and they don't really mix as well together as they should (IMO)

There's the white, steel like texture of iron blocks, doors and trapdoors; The typical metal grey iron bars and the dark blue-ish texture of chains and lanterns.

It would be really cool if these blocks had a texture revision to look more alike (at least a bit)

Alternatively, netherite doors/trapdoors and bars to match the chain textures could also solve some of the problems
