feat(ui): add community feedback banner to login view (#104)

* feat(ui): add community feedback banner to login view

* Update src/views/LoginView.vue

I was originally working on this from the main Caldera branch when i wrote this PR, switched to magma once Github CLI gave me submodule issues. AI is very picky, does this really need underline link to the discord and mitre email?
