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.
