feat: Add deployment to a staging environment

Added staging.nginx.nix modeled on prod.nginx.nix, configuring nginx as a
local staging server. Updated deploy.sh to target either staging or prod
over SSH. Consolidated shared configuration between the two nginx nix
files and between the staging and prod deploy paths in deploy.sh.
