Manage grocery store inventory by restocking items and applying discounts based on stock levels. You'll use loops to update each item's status.

• Use a for loop to go through each item in the inventory dictionary.
  • For each item, get its current stock, minimum required stock, restock quantity, and sale status.
• Use a while loop to restock the item until its stock is at or above the minimum. Increase the stock by the restock quantity on each iteration.
• After restocking, check if the stock exceeds discount_threshold and the item is not yet on sale. If so, set its sale status to True.
• If the item is already on sale and still exceeds the threshold, print a message indicating it is already discounted.

Output Requirements

• For each item, print:
  Processing <item>...
• If a discount is applied:
  <item> stock has exceeded <discount_threshold> units. Discount applied.
• If the item is already on sale:
  <item> is already discounted.
• After all items are processed, print:
  Final Inventory Report
  Then, for each item:
  <Item>: <current_stock> units (Min: <min_stock> units) - On sale: <on_sale>
