HBM Doors: Refreshed/ClosedSecurity

• Added Ultra High Performance Concrete, a six-shade concrete family: the original texture plus five progressively darker grayscale shades.
• Every variant takes three real hours of continuous mining with any tool.
• Blast resistance is an explicit allow-list: only ICBM Classic nuclear, antimatter and red matter warheads can damage it. Thermobaric, TNT, creepers and every other explosion are fully resisted.
• Added a decorative UHPC Panel set with the same six textures and vanilla-concrete hardness, so it breaks and blasts apart normally.
• The hard set carries the GBU-57 not included tooltip; the soft panels do not.
• Registered under the concrete and blockConcrete ore dictionary entries and appended to the NTM Doors creative tab.

Weapons Relay Key

• Added the Weapons Relay Key, a red creative key with the tooltip Hard lock weapons so enemies can't disarm them.
• Sneak + Right Click opens a mode screen.
• Regular Bounding links any explosive block to Redstone Gates: sneak + Right Click an explosive to start, then gates to link. A powered gate triggers the explosive immediately.
• Dead Man's Hand hard-locks the explosive: a player without the matching key detonates it by right-clicking, left-clicking, breaking it, or placing/breaking a block next to it. The key holder can mine it safely.
• Works with any explosive block.

Spatial Disrupter

Addd the Spatial Disrupter, a decorative machine block: blue/red emblem on the sides and a grey plate on the top and bottom.

• Tooltip: Weakens the structural integrity of UHPC.
• Right-click opens a single-action screen with the warning WARNING THIS OPERATION CANNOT BE REVERSED.
• Activating it scans a 16×16 chunk area and converts every hard UHPC block into the soft UHPC Panel of the same shade, then consumes itself with particles and a sound.
• The machine is bedrock-hard: it cannot be mined, blown up or pushed, and only its own completed operation removes it.
• The scan is incremental and skips unloaded chunks. A 131,072-block UHPC field converted in about 4.6 seconds at 20 TPS in the dedicated-server stress test.
