feat: add in-stack Euro-Office integration (15.1.0)

Optional compose.eurooffice.yml overlay that runs the Euro-Office document
server (ghcr.io/euro-office/documentserver) inside the stack, with its own
Postgres and RabbitMQ services. The document server schema is seeded into that
Postgres on first init (eurooffice-createdb.sql). Postgres is internal-only with
trust auth, so the only managed secret is the JWT. A custom entrypoint injects
the JWT from the Swarm secret, then execs the image's entrypoint.

Additive: no effect on existing installs unless enabled. Adds install_eurooffice()
plus EUROOFFICE_DOMAIN / SECRET_EUROOFFICE_JWT_VERSION config.

+### Euro-Office Integration
+
+Euro-Office is the AGPL fork of OnlyOffice that powers "Nextcloud Office" from
+Nextcloud 34 onwards. Like OnlyOffice it uses a client-side document-server
+architecture, so a separate document server is required — but this overlay runs
+that document server **inside the same stack**, so there is no external host to
+manage. The browser talks to it directly, so it needs its own public HTTPS
+domain (`EUROOFFICE_DOMAIN`) with a DNS record pointing at this host.
+
+`abra app config <app-name>`
+
+Enable the overlay and set the document server's domain:
+```
+COMPOSE_FILE="$COMPOSE_FILE:compose.eurooffice.yml"
+EUROOFFICE_DOMAIN=eurooffice.example.com
+APPS="$APPS eurooffice"
+SECRET_EUROOFFICE_JWT_VERSION=v1
+```
+
+The overlay runs the document server with its own Postgres and RabbitMQ services
+(the image's bundled Postgres is unreliable). The document server schema is
+seeded into that Postgres automatically on first init (see
+`eurooffice-createdb.sql`). The Postgres is internal-only and uses trust auth, so
+the only secret to manage is the JWT; generate it, deploy, then wire up the
+Nextcloud app:
+
+* `abra app secret generate -a <app-name>`
+* `abra app deploy <app-name>`
+* `abra app cmd <app-name> app install_eurooffice`
+
+> Note: the document server needs ~4 GB RAM (8 GB for multi-user) and pulls the
+> `ghcr.io/euro-office/documentserver` image, which currently only publishes a
+> `latest` tag (no semver / Renovate pinning yet).
