=== Fixing Delivery Rounding (ROUND instead of CEIL) ===

Updating all delivery quantities to use ROUND (nearest) instead of CEIL (always up)...
Done!

Verification:
  School: SCH-0001
  Commodity: RICE
  Planned: 157.021
  Delivery: 157.00

✅ Now using smart rounding:
   - 157.02 → 157 (not 158)
   - 157.50 → 158 (rounds up)
   - 157.49 → 157 (rounds down)
