Ironforge Great Forge lava, magma water rendering, LavaSteam particle effects

- Add magma/slime rendering path to water shader (fbm noise, crust/molten/core coloring)
- Fix WMO liquid height filter rejecting high-altitude zones like Ironforge (Z>300)
- Allow interior WMO magma/slime MLIQ groups to load (skip only water/ocean)
- Mark LAVASTEAM.m2 as spell effect for proper additive blend, hide emission mesh
- Add isLavaModel flag for M2 ForgeLava/LavaPots UV scroll fallback
- Add isLava material detection in WMO renderer for lava texture UV animation
- Fix WMO material UBO colors for magma (was blue, now orange-red)
