Legacy Compose applications keep the old name of an external volume. The
deployment log now tells the user why and how to move to the external
volume. The storage page shows external volumes as a read-only list.

Switching an external volume from the old <uuid>_<name> volume to the
declared external volume on redeploy could make an app look as if it
lost its data (for example a database that initializes a new, empty
data directory).
- If a resource already has the storage entry with the old generated
name, the parsers keep using that volume and show a warning in the
deployment log and the service start log, with the steps to switch.
- Without that entry (new resources, or external volumes added later)
the external volume is used as declared.
- Deleting the old storage entry (storage page) switches to the
external volume on the next deployment; the storage entry shows a
note about it.
- Legacy Compose applications (parser versions 1 and 2) never stored
their volumes, so they keep the old volume names.

Compose volumes declared with external: true (or external: {name: x})
were renamed to <uuid>_<name>, so containers got a new empty volume
instead of the existing one. All Compose parsers (applications,
previews, services, and the legacy parsers) now use them as written:
no uuid prefix, no preview suffix, the top-level declaration kept, and
no tracking row, so Coolify never removes a shared external volume.
External volume names must be literal; ${VAR} names are rejected.
Existing <uuid>_<name> volumes and their rows are kept on redeploy.
