[Feature] Add Alerts History page

[svenvg93]

📃 Description

This PR introduces a new page to track the history of all alert results. For now, the page is located under the Settings section, as I could not find a better place for now.

🪵 Changelog

➕ Added

• alert_history collection to store alert result history
• alert_history module to manage related logic
• UI page with a table to view, export, and delete alert history

Great idea! I'll check this out soon.

How long do you think we should we retain these? 60 days?

[svenvg93]

Great idea for the retention, I made it user configurable for 1,3,6,12 months. With default to 3 months.

As well do you think the settings page is the right place for now?
By now it might make sense to add an side bar and move the settings, etc to there, as it makes its easier to group new pages, looking the new pages added in #937 and discussed in #972 as well.

Thanks, I like this feature and want to get it in the 0.12.0 release so I'll pick it up from here.

We'll just leave it in settings for now but I agree a sidebar would make sense in the future.

Thanks again, this is merged now and is definitely a useful feature.

I'm going update tests and docs for the next release, then I'll loop back around to the other PRs afterwards 👍
