Replace calls to `flask db upgrade` with `alembic upgrade head` in SimpleLogin install and update scripts so migrations are executed via Alembic in the virtualenv. For Discourse, remove in-place puma.rb sed tweaks (socket bind and stdout redirect) and update the systemd ExecStart to run `pitchfork -c config/pitchfork.conf.rb` instead of invoking puma directly, using Discourse's recommended process manager.
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.
Discourse install: add PG_DB_EXTENSIONS="vector" to setup_postgresql_db and remove the separate CREATE EXTENSION psql call; also remove curl and git from the apt install list and drop the automatic admin bootstrap messaging. SimpleLogin install: source /opt/simplelogin/.env before running migrations and add EnvironmentFile=/opt/simplelogin/.env to the systemd unit files (gunicorn, email_handler, job_runner) so services inherit environment variables.
Bump PostgreSQL target from 16 to 17 in discourse-install.sh and make pg_hba.conf lookup dynamic (uses find) instead of a hardcoded path, ensuring compatibility with systems where the data directory path differs. Also add EMAIL_SERVERS_WITH_PRIORITY and POSTFIX_SERVER entries to the SimpleLogin .env to configure local mail delivery (set to localhost).
Set NOT_SECURED=true in postiz install script for local/non-secured setups. In simplelogin install, detect the venv site-packages path and create a minimal newrelic package stub (newrelic/__init__.py and newrelic/agent.py) with no-op record_custom_event and initialize functions to avoid import errors when New Relic is not present.
