Apply reference colors to home stats section (Task #24)

The "إحسانكم لعام 2026" statistics section rendered its heading and big
numbers in the bright brand green (text-primary). The reference uses a
deeper forest green for those text elements, keeping the brighter green only
for the icons/leaf.

Change (artifacts/ehsan-poc/src/pages/home.tsx):
- Heading <h2> and each stat number <div>: text-primary -> text-[#14573A]
  (deep forest green sampled from the reference image).
- Leaf accent and the three card icons: kept text-primary (#1B8354).
- Subtitle and labels: unchanged (text-muted-foreground gray).

No layout/order changes; works in AR (RTL) and EN. tsc --noEmit clean;
verified visually in the preview.
