feat: Added ability to click another user to observe them (sync scroll position) (#2858)

* feat: Added ability to click another user to observe them, mainly for fun

* language, lower debounce, prevent tooltip from hiding when toggling observation

* fix: Don't allow observing self, added banner at top of screen

* Dont edit tooltip as it's confusing between our actions and theirs

* snapshots
