WRONG YELLOW — FAULT DRY SLAB FIX

Problem:
Minecraft structure placement may waterlog slabs when a template overlaps existing water, even when the saved state is waterlogged=false.

Fix:
Before each fault or wall template is placed, generated helper functions put full smooth_stone blocks exactly at every saved smooth_stone_slab coordinate. The template then immediately replaces those temporary full blocks with the original slab states.

This preserves every slab type/orientation and avoids clearing the complete fault volume.

Generated helpers:
- fault: 996 slab position(s)
- fault-wall_a1: 1 slab position(s)
- fault-wall_a4: 1 slab position(s)
- fault-wall_a5: 1 slab position(s)
- fault-wall_b1: 1 slab position(s)
- fault-wall_b2: 1 slab position(s)
- fault-wall_b3: 1 slab position(s)
- fault-wall_b4: 1 slab position(s)
- fault-wall_b5: 1 slab position(s)
- fault-wall_c1: 1 slab position(s)
- fault-wall_c3: 1 slab position(s)
- fault-wall_c4: 1 slab position(s)
- fault-wall_c5: 1 slab position(s)
- fault-wall_d1: 1 slab position(s)
- fault-wall_d2: 1 slab position(s)
- fault-wall_d3: 1 slab position(s)
- fault-wall_d4: 1 slab position(s)
- fault-wall_d5: 1 slab position(s)
- fault-wall_e2: 1 slab position(s)
- fault-wall_e4: 1 slab position(s)
- fault-wall_e5: 1 slab position(s)
