Subject: [PATCH] perf: optimize dynamic array creation in SamplingErrorModule

Replaced Array.from calls in SamplingErrorModule.tsx with more efficient
alternatives: a static array for the grid cells and new Array().fill()
for the dynamic simulation cells. This reduces memory allocations and
CPU overhead during component renders.
