chore: Remove high vulnerabilities (M2-9964) (#181)

- `npm audit fix` to remove vulnerabilities
- Upgrade Node `22.15.x` → `24.x.x`
- Update ESLint `8.57.1` → `9.39.1`
- Migrate `.eslintrc.js` → `eslint.config.js`

`npm audit` before:

    10 vulnerabilities (1 low, 4 moderate, 5 high)

`npm audit` after:

    3 vulnerabilities (1 low, 2 moderate)

To test changes:

1.  Configure `keys` and `outputs` as described in README.

2.  Run tests.
    
        npm test

3.  Run app.
    
        docker build -t mindlogger-report-server:latest .
        docker run -d -v "./keys:/app/keys" -p "3000:3000"  --name mindlogger-report-server mindlogger-report-server:latest
