feat: editor_notes + /api/stats/live + tokens в getArticleBySlug

- БД: таблица editor_notes (title/content/author/tags/is_pinned/is_published)
- routes/notes.js: CRUD заметок редактора
- /api/stats/live: latest article, processing job, активность за 7 дней
- getArticleBySlug: JOIN с generation_jobs для tokens_in/out
