librelad 65167463f9 fix(chat apps): tag every service so its IP actually substitutes
Installing rocketchat failed with

    invalid IPv4 address: ParseAddr("IP_DATA_2"): unable to parse IP

ipUpdateComposeTags allocates one IP per SERVICE_TAG_N annotation and fills
IP_TAG_i only where SERVICE_TAG_i exists. The four new apps tagged only their
primary service, so every sidecar — matrix's postgres, mattermost's postgres,
rocketchat's mongo, and fifteen of stoat's sixteen — kept a literal IP_DATA_n
in the deployed compose and docker refused to create the container.

Tag every service that carries an ipv4_address, index-aligned with its IP_TAG.
For stoat that also meant moving caddy from SERVICE_TAG_1 to _6 so the indices
line up with the IPs rather than the reading order.

mastodon had the same latent break (IP_TAG_2 and _3 untagged) and is fixed the
same way — it would have failed on first install for the same reason.

SERVICE_TAG carries the compose *key*, not container_name: 'libreportal app
restart <app> <service>' passes it to 'docker compose restart', which only
understands keys.

This installs the Synapse homeserver on Postgres plus the Element web client, on their own subdomains.

# - access: 'public' (internet accessible), 'private' (local network only), 'disabled' (not running)
# - protocol: 'tcp' or 'udp'
# - login: if true, this port requires basic-auth via Traefik (only meaningful when traefik=true)
# - traefik: if true, Traefik handles this port (reverse proxy)
# - webui: if true, this port serves the main web interface
# - description: human-readable description of the service
#
# Two hosts, on purpose. Port 1 is the homeserver API on matrix.<domain>, which
# becomes server_name — so user IDs read @alice:matrix.<domain>. Port 2 is the
# Element web client on element.<domain>. Keeping them apart means Synapse can
# answer /.well-known/matrix/server for itself and federation needs no
# delegation from the apex domain, which this app has no way to configure.
#
# Port 1 must NOT be marked login=true: /_matrix is the client and federation
# API and basic-auth in front of it locks out every client and every peer.
