feat: Add security configuration options to Electron. Add progress bar. Add tabbing id.

* Developer experience - Add progress bar that appears on the Docker icon (particularly useful for those with slow connection or local machine)

* Add tabbing identifier set to 'parity' so it groups projects with same identifier

* Security - Electron window setContentProtection to true to prevent other apps being able to access it

* Security - webPreferences.enableRemoteModule to false to prevent unsolicited access

* Add shadow to taskbar app
