Package mobymask-v2 stack web-apps similar to laconic-console app (#310)

* Build MobyMask web-app at container build step

* Fix web-app start script to use env variables in config

* Replace variables in built web-app files

* Use published mobymask-ui package from gitea

* Use published react-peer/test-app from gitea

* Remove local gitea publish TODO
