* Refactor status icon and tooltip updating.
* Initialize tooltips once and in one place (except for the individual selection screen, where selection cards are created dynamically) by setting tooltip attributes in index.html.
* Change `updateIndividualSelectScreen()` to hiding and showing selection cards to avoid destroying the tooltip handlers.
* Move `pointer-events: none` property to .opponent-image so that opponent suggestion status tooltips work.
* Change placement of tooltips so they fit on screen.
