BUG: "Open Original File" button in Media Info Panel shows no action

### What happened?

### Description
The **`Open Original File`** button in the `Image Details` panel fails to open images in the system's default viewer. Even though the backend provides the correct absolute path, the frontend action is either silent or blocked by security errors.

### How to reproduce
- Launch PictoPy and go to the Home gallery.
- Select an image and click the **`Show Info (Info icon) button`**.
- Click the **`Open Original File`** button at the bottom of the panel.
- Observation: No external application opens, or a `Failed to open file` error appears in the console.


### Root Cause
- **Migration Gap**: The code uses `open() from @tauri-apps/plugin-shell`, which is deprecated/restricted in Tauri v2 for opening local file system paths.
- **Missing Permissions**: The Tauri capabilities configuration lacks the explicit `opener:allow-open-path` permission.
- **Missing Scope**: Tauri v2 requires an explicit scope `(**)` to authorize the opener plugin to access local file paths.

### Potential Fix
- **Frontend** : Migrate from `plugin-shell` to `@tauri-apps/plugin-opener` and use `openPath(currentImage.path)`
- **Configuration** : Update the app's capability file `migrated.json` to include the scoped permission:

```JSON
{
"identifier": "opener:allow-open-path",
"allow": [{ "path": "**" }]
}
```
