Last user modified (#7886)

* feat: Add user modified functionality

Closes https://github.com/FreshRSS/FreshRSS/issues/7862

Changes proposed in this pull request:

This is an implementation of the proposed feature. It allows entries to have a new field that will be updated whenever an item is marked as read/unread or bookmark/removed from bookmarks. And a new sort criteria to sort by it.

How to test the feature manually:

1. Mark items from a feed as read/unread
2. Mark items from a feed as bookmark / remove bookmark
3. Sort by the new criteria
