Feature/93 support prod builds

Why??

We'd like a way to deploy the application to a Production environment

both the dev and prod envs require CORs - this keeps everything consistent
the backend prod build API uses HSTS and enforces HTTPS
the frontend prod build also enforces HTTPS
the entire stack uses valid SSL certs, even for a dummy prod (ie. one deployed on localhost)
the database and logging for the prod backend should reflect a prod build
- slim down the log details
- maria db is accessed over the docker net and kept hidden

improved the entire docker build process
all READMEs updated
removed Nginx Proxy Manager, slim version of nginx utilised instead
mkcert and localtest.me docs and commands added to support locally testing the production deployment process
prod Vite and .NET configs added
- prod launchSettings config added to .NET backend for testing prod build with debugger
- prod Vite settings are for equiv.
corrected deps vs. devDeps in package.json
added .NET Dockerfile pipeline
