Fix chai 6.x compatibility - replace default imports with namespace imports

[Copilot]

Motivation/Description of the PR

Chai 6.x removed the default export, breaking test imports that used import chai from 'chai'. Updated all chai imports to use namespace imports for compatibility.

Before:

import chai from 'chai'  // ❌ SyntaxError: does not provide an export named 'default'
chai.should()

After:

import * as chai from 'chai'  // ✅ Works with chai 6.x
chai.should()

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• google.com
  • Triggering command: node /home/REDACTED/work/CodeceptJS/CodeceptJS/bin/codecept.js run --config /home/REDACTED/work/CodeceptJS/CodeceptJS/test/data/sandbox/codecept.bdd.js --grep @fail --steps (dns block)
• googlechromelabs.github.io
  • Triggering command: node install.mjs (dns block)
• https://storage.googleapis.com/chrome-for-testing-public/138.0.7204.168/linux64/chrome-headless-shell-linux64.zip
  • Triggering command: node install.mjs (http block)
• jsonplaceholder.typicode.com
  • Triggering command: node /home/REDACTED/work/CodeceptJS/CodeceptJS/node_modules/.bin/mocha test/unit --recursive --timeout 10000 --reporter @testomatio/reporter/mocha (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
