Improve AJAX link and modal confirm dialog (#25210)

Clarify the "link-action" behavior:

>  // A "link-action" can post AJAX request to its "data-url"
> // Then the browser is redirect to: the "redirect" in response, or
"data-redirect" attribute, or current URL by reloading.

And enhance the "link-action" to support showing a modal dialog for
confirm. A similar general approach could also help PRs like
https://github.com/go-gitea/gitea/pull/22344#discussion_r1062883436

> // If the "link-action" has "data-modal-confirm(-html)" attribute, a
confirm modal dialog will be shown before taking action.


And a lot of duplicate code can be removed now. A good framework design
can help to avoid code copying&pasting.
