I have updated all references of "Impress" to "Meet". Migrations were manually updated and not regenerated. Never-mind, they all will be squashed before the first release. I have also searched for reference to "Magnify", and replaced them by "Meet". While updating the backend sources, I have also fixed other parts of the project, namely: - Compose file - Github documentation and CI - Makefile commands
