[Feature Request] Clear cached images when deleting notifications

[imjoeyli]

Hi, thank you for maintaining Bark app.

I noticed that the app’s cache size gradually increases over time. Deleting notifications does not seem to remove the related cache. I suspect this cache mainly comes from notifications that include images.

Could Bark remove the cached images associated with a notification when that notification is deleted?

This would help reduce storage usage and avoid keeping old notification images that are no longer needed.

Thanks for considering this.
