fix: initialize chai.should() in Appium tests

The test was failing with 'Cannot read properties of undefined (reading "be")'
because chai's should assertion style was not initialized.

Added chai.should() call after imports to enable should-style assertions
throughout the test file.

Fixes test: device lock : #seeDeviceIsLocked, #seeDeviceIsUnlocked
