Move Images to Trash

# Objective

Implement funcitonality that allow users to delete images file. The Images should be stored in a specificed folder who has a name trash.

# Requirements:

- Allow users delete images.
- The Images goes to trash folder.

# Steps to Implement

1. Create a `POST` endpoint `/trash`
2. Send in body can be:
``` json
{
"image_ids": ["image_id_1", "image_id_2", "image_id_3"]
}
```

3. Check if each image_id exists in the database.
4. If an image_id is invalid (not found in the database), return a partial success response with the IDs that were successfully processed.
``` json
{
"message": "Some images could not be moved to trash.",
"trashed_images": ["image_id_1"],
"failed_images": ["image_id_3"]
}
```
6. Return the result of the operation, indicating which images were successfully moved to the trash and which were not.
```json
{
"message": "Images moved to trash successfully.",
"trashed_images": ["image_id_1", "image_id_2"],
"failed_images": []
}
```
7. Return error
```json
{
"message": "Invalid request.",
"error": "No image IDs provided."
}
```

Start by locating the TypeScript API entry point, the image database model, and the existing image-storage code. Add the POST /trash flow using the specified image_ids payload, then verify responses for successful moves, invalid IDs, and an empty request against the repository's available checks.
