Fix full-screen blue tint when staring at a secret's highlight box

[kovalancik06-max]

Summary

• Fixes the whole screen becomes tinted blue when staring at a secret #24 — the screen shines/tints (e.g. blue for chest secrets, whose highlight color is Color(2, 213, 250)) when looking directly at a nearby secret waypoint, but is fine looking away.
• Root cause: Waypoints.onWorldRender disables both depth testing and face culling before calling WaypointUtils.drawFilledBoundingBox(...) for the secret's highlight box. With culling off, every face of the box is rasterized, including the ones facing into the box; with depth testing also off, nothing hides them. When the camera is inside or right up against the box (exactly what "staring at" a nearby secret means positionally), those inward-facing walls end up covering the whole viewport in the secret's translucent color.
• The box's vertices are already wound so each face's outward normal is correct (verified the bottom face's winding by hand: (maxX-minX,0,0) × (0,0,maxZ-minZ) = (0, -dx*dz, 0), i.e. normal points outward/down as expected) — so standard backface culling was never the problem, it was just switched off for this draw call along with the (deliberately double-sided) beacon beam.

Fix

• Move GlStateManager.disableCull() to after the filled-box draw call, so the box renders with the default (enabled) culling state. This hides the inward-facing walls when the camera is inside/near the box, exactly like a normal "outline" highlight, while the beacon beam right below keeps its own disableCull() since it's meant to be visible from both sides.

Test plan

• Verified the box's face winding produces outward-facing normals, so enabling culling doesn't accidentally hide the box from legitimate outside viewing angles.
• Change is scoped to moving one existing statement a few lines down — no new state, no behavior change for the beacon beam or any other code path.
• Not able to run a full ForgeGradle 1.8.9 build or reproduce the exact camera angle in a live Hypixel dungeon in this environment, so please confirm visually before merging — happy to adjust if there's a specific secret type/orientation where this doesn't fully resolve it.
