## Summary
- Fixes `banks:set-logo` for JPEG images by adding a `makeJpeg()` test
helper and a full JPEG test case — the pipeline was working but
completely untested, meaning any regression would go undetected
- Implements `PromptsForMissingInput` so the command interactively
prompts for `bank` and `url` when they are not passed as arguments
## Summary
- Adds `banks:set-logo {bank} {url}` artisan command to download,
process, and assign a logo to a bank by UUID
- Installs `intervention/image:^3.0` (GD driver) for image processing
- Image is validated to be square (returns an error if not), resized
down to max 250×250px if needed, stored as PNG on the `public` disk at
`banks/logos/{uuid}.png`, and the bank's `logo` field is updated with
the public URL
## Usage
```
php artisan banks:set-logo <bank-uuid> <image-url>
```
## Tests
7 feature tests covering success, no-resize, bank not found, HTTP
failure, non-image content type, non-square image, and invalid image
content.
