Fix Docker deployment: restore HTTPS, auto-run plugin migrations, install core plugins only

- Restore original HTTPS config in docker-compose files (gunicorn + gevent DOES support SSL)
- Add plugin migration step to docker-entrypoint.sh (fixes missing plugin tables on first deploy)
- Install only core plugins on bootstrap (backups, computers, endpoints, guides, knowledgebase, machines, network, notifications, printers, slides, tools, warranty)
- Set FLASK_ENV=production to disable Werkzeug debugger

Bug: bootstrap-plugins.sh installed ALL plugins but didn't run migrations, causing
'Table does not exist' errors. Now installs core plugins only and runs 'flask plugin
upgrade-all' after bootstrap.

Optional plugins (employees, geenforce, measuringtools, printedparts, usb) can be
installed later via Settings > Plugins.
