Add REST API endpoints for application persistent storage (volumes)

[jcserracampos]

Description

The Coolify REST API currently has no endpoints for managing persistent storage (volumes) on applications. The LocalPersistentVolume model, the Application->persistentStorages() relationship, and the deployment job that mounts volumes all exist — the only missing piece is the API surface.

Currently, persistent storage can only be managed through the Livewire UI components (app/Livewire/Project/Service/Storage.php). Programmatic deployments have no way to add, list, update, or remove volumes via the API.

Additionally, custom_docker_run_options with --volume is silently ignored by convertDockerRunToCompose() in bootstrap/helpers/docker.php (not in the supported options whitelist), which makes this gap even more impactful — there is no API workaround at all.

Proposed Solution

Add 5 new endpoints following the same pattern as the existing environment variable endpoints:

Method	Path	Description
GET	/applications/{uuid}/storages	List all persistent storages
POST	/applications/{uuid}/storages	Create a new persistent storage
GET	/applications/{uuid}/storages/{storage_id}	Get a single storage by ID
PATCH	/applications/{uuid}/storages/{storage_id}	Update a storage
DELETE	/applications/{uuid}/storages/{storage_id}	Delete a storage

Use Case

Any tool or SaaS that deploys applications programmatically via the Coolify API needs to attach persistent volumes (e.g., for config directories, data files, credentials). Without these endpoints, the only option is direct database manipulation, which is fragile and unsupported.
