[feature] Screenshot + Upload to S3 and Timed Reports

It would be ideal to take a screenshot and upload it to S3 or another Cloud -- perhaps on device, and only keep the last 25-100 screenshots -- and be able to attach them inside of a notification of any kind or at least get a public link to view the screenshot embedded in the notification.

I'd also like to be able to get "timed reports", as in see all changes and screenshots taken within the past X cycles or minutes, just in case we are missing something or configure the filters incorrectly.

I'd be happy to contribute code. Shouldn't be too hard.

The issue names screenshot capture, S3 or other cloud storage, notifications, retention, and timed reports but identifies no files, tests, or entry points. Start by tracing the existing screenshot, notification, and report-related paths, then clarify the storage, retention, scheduling, and delivery requirements. Done should include agreed behavior for both screenshot attachments or links and reports covering a defined time window.
