Subject: [PATCH] Update Hardhat tutorial to ethers v6 API

The examples use ethers v5 API (`contract.deployed()`, `contract.address`), but `@nomicfoundation/hardhat-toolbox` ships with ethers v6. Copy-pasting causes tests and deployment to fail with `TypeError: contract.deployed is not a function`. Also, `hardhat.config.js` calls `require("dotenv")`, but dotenv is not installed in the dependency setup step.

Fixes:
- Added `dotenv` to the `npm install` command
- `await contract.deployed()` > `await contract.waitForDeployment()`
- `contract.address` > `await contract.getAddress()`

**Result:** The tutorial now matches the current Hardhat Toolbox, users can run setup, tests, and deployment without API fixes.
