EIO Darksteel Backport Fixes

Changed

• Fixed Carpeting mode so it can drive legacy flat-area mining independently from the Explosive toggle while still using the installed Explosive upgrade level as its mining force.
• Carpeting without Depth now mines a horizontal carpet-style layer around the broken block instead of falling back to the normal explosive cube.
• Depth now only changes the explosive/carpet shape when its own toggle is enabled.
• Corrected the Empowered V upgrade crafting recipe to use enderio:ender_resonator, matching the Ender IO 1.12 skullEnderResonator recipe intent.
• Added Dark Steel -> End Steel and End Steel -> Stellar Alloy tier upgrade smithing recipes for swords, pickaxes, and axes.
• Added matching Ender and Stellar tool upgrade template items for swords, pickaxes, and axes.
• Updated armor tier upgrade icons and added tool tier upgrade icons with the blank upgrade as the background and the upgraded armor/tool piece overlaid in front.
• Added English and Brazilian Portuguese item names for the new tool tier upgrade templates.

Notes

• Existing armor tier upgrade behavior is unchanged; upgraded items still preserve installed Dark Steel upgrades, stored FE, and inventory NBT through the custom tier-upgrade smithing recipe.
