Normalize compose: experiments/*, db-backup, autogenerate-hosts

- db-backup: IMAGE_VERSION for image tag; service key order; networks order
- autogenerate-hosts: explicit autogenerate-hosts-net
- experiments: consistent image/container/hostname/restart/env_file/volumes/networks order
- avahi: drop invalid depends_on mdns_repeater
- frigate: comment published port 5000; trim tmpfs comment
- matrix: synapse/synapse, element-web/element-web (match service names)
- nextcloud: image tag env, hostname/container_name, README + gitignore/rsync
- qdrant: IMAGE_VERSION default, README + .env.example (no required env_file)
- portainer/grafana: no env_file (vars are for host-side backup scanner only)
- comfy-ui: GPU_COUNT default 1, no env_file; stable-diffusion keeps env_file
- rtlamr2mqtt: config under config/rtlamr2mqtt.yaml.default + mount path
- camera2prusa: bridge network + env_file + IMAGE_VERSION in .env.example
- chronograf/influxdb/openwakeword/telegraf/trimetd/rtl_433/homebox: tidy
