1. Rewrite `dirauto.ts` to `observer.ts`.
* We have been using MutationObserver for long time, it's proven that it
is quite performant.
* Now we extend its ability to handle more "init" works.
2. Use `observeAddedElement` to init all non-custom "dropdown".
3. Use `data-global-click` to handle click events from dynamically
loaded elements.
* By this new approach, the old fragile selector-based
(`.comment-reaction-button`) mechanism is removed.
4. By the way, remove unused `.diff-box` selector, it was abused and
never really used.
A lot of FIXMEs in "repo-diff.ts" are completely fixed, newly loaded
contents could work as expected.
Modify Diff View FileTree to show all files
## Changes
* removes Show Status button on diff
* uses `git diff-tree` to generate the file tree for the diff
* doesn't reload the diff tree each time we load more files in the
preview
* selecting and unloaded file will keep loading until that file is
loaded
* removes `DiffFileList.vue` and "Show Stats" in diff options
## Open Questions
* selecting and unloaded file will keep loading until that file is
loaded. Is this behaviour okay? It matches what github does.
### Demo
In this demo I set `git.MAX_GIT_DIFF_FILES=1` in my `app.ini` to
demonstrate a worst case example. In most cases the behaviour isn't
nearly as jarring as we load a bunch of files at a time.

Fix#32684, regression of #32596 (side-effect of jQuery removal: jQuery could tolerate non-existing elements)
And fix another regression bug from #30453 (initCompReactionSelector double-init)
None of the frontend js/ts files was touched besides these two commands
(edit: no longer true, I touched one file in
61105d0618
because of a deprecation that was not showing before the rename).
`tsc` currently reports 778 errors, so I have disabled it in CI as
planned.
Everything appears to work fine.
