Level 23: Implement GET /items/:id

• Look up a record by id and return it with 200 when found.
• Respond with 404 and a friendly error JSON when the id is missing.
• Don’t forget: Use your own resource path and variable names, not the example items.

Show Me: find item by id

const item = itemsStorage.find((entry) => entry.id === req.params.id);
if (!item) return res.status(404).json({ error: 'Item not found' });
res.json(item);
