[samatstariongroup]

Prerequisites

• I have written a descriptive issue title
• I have verified that I am running the latest version of the COMET-WEB
• I have searched open and closed issues to ensure it has not already been reported

Description

the solution currently contains selenium based tests (very minimal) these shall be replaced with end-to-end tests using playwright. The intent is that these tests can be run to verify that all features of the app remain working using a running comet server and that these tests are executed using a gh action that deploys the comet server in a docker container, starts the web app and then executes the playwright tests, Part of this feature is to determine what tests makes sense to have very high coverage and keeping maintenance doable

Steps to Reproduce
