Fix cookie handling in Firefox when using HTTP

[floreks]

Fixes #5126

I have also fixed argument handling when running dev build. The old way of passing arguments to npm did not work. New way:

DASHBOARD_ARGS="enableInsecureLogin;enableSkipLogin=true npm run start"

Parameters are split using a semicolon and for non-boolean values use equals operator to pass a value. For boolean values it is optional.
