Web UI frontend automated browser tests (#2223)

* First pass at basic browser tests for #1926

* Run tests against dev web server not go server

* Bundle the web code into the server before running tests

* Move cypress UI tests into its own npm project + add tests

* Add additional tests + wire up with cypress dashboard

* Limit concurrency of workflow jobs

* Temporarily comment out some tests that do not pass in mobile. Will fix later.
