Normalize event-manager compose; add to install-chaos Tier 2

apps/event-manager/docker-compose.yml:
- IMAGE_TAG -> IMAGE_VERSION; add ${REDIS_IMAGE_VERSION:-7-alpine} for redis
- Add container_name/hostname to redis (event-manager-redis) and sidekiq
  (event-manager-sidekiq)
- restart: always -> unless-stopped on redis and sidekiq
- Internal redis network em-redis -> event-manager-redis-net
- Use service_healthy condition on depends_on
- Remove proxy network from sidekiq (background worker, no HTTP)
- Unify sidekiq log volume to ../../log/event-manager (same as web)
- Rename network alias mailer -> mail to match project convention
- Delete backup file docker-compose.yml~
- Add .env.example, README.md, .rsync-exclude

bin/install-chaos.sh:
- Add event-manager to Tier 2 (needs proxy, db, mail/postfix-net)
