23: Global setup for Playwright, and some basic Playwright UI tests

[adigidh]

fixes #23

Summary of changes:

• Setup Playwright (installed packages, setup configuration)
• Created a simple setup test that performs a real login with an e2e account and saves the storage state so the next tests can run in an authenticated state. Using env variables for username, and password so these can be supplied from the user.
• Basic tests for login page
• NPM scripts for execution on local
• Docs in development markdown for running these tests locally

Example report after running the tests locally:

@adigidh PR looks good to me. Can you please add instructions for running the test cases in the development doc in docs directory. Once you update the docs, PR it good for merge, so please mark it ready for review.
