Replaces the raw manga-id / chapter-id UUID inputs with a real picker:
- Search a manga (debounced, reuses listAdminMangas) → result rows show
title + chapter count; "Queue manga" enqueues the whole manga.
- Expand a result to load its chapters (listAdminChapters) and "Queue
chapter" enqueues a single chapter.
- Keeps the "Queue all (whole library)" action and a single global
"include already-analyzed" toggle applied to every action; per-action
busy state + a result message naming what was queued.
Tests: rewrote the Playwright spec to drive the search → manga/chapter
flow (whole library, search+queue manga, expand+queue chapter with
include-analyzed). svelte-check + build clean.
