Split Discourse services; update SimpleLogin setup

Add DISCOURSE_PUMA_BIND to Discourse env and switch the discourse.service to load EnvironmentFile=/opt/discourse/.env. Create a separate systemd unit for Sidekiq (discourse-sidekiq.service), enable both services, and adjust messaging to "Services". In simplelogin install: remove git from apt list, bump PostgreSQL setup from 16 to 17, and export FLASK_APP=server before running migrations/initialization so Flask commands run with the correct app context.
