fix: remove dotenv dependency from NUT test to avoid dependency conflicts

- Removed dotenv import and config() call from componentLocalPreview.nut.ts
- Using process.env directly instead of dotenv.config()
- This avoids the mocha/cliui dependency conflict that was preventing CI tests
- Now we can test if NUT test files cause @lwrjs/api issues without package.json changes
