Adds an ordered chapter layer to series. Reading order becomes (series_chapter.chapter_number, series_page.page_number); a chapter may be a placeholder reserving a slot, and carries an optional parsed stated-page range used to flag missing-page gaps. An image still lives in at most one series ⇒ one chapter (image_id stays UNIQUE). - models: series_chapter; series_page gains chapter_id (NOT NULL, cascade) + stated_page. Migration 0040 backfills every existing series into one auto-chapter holding its current flat pages — no data loss. - SeriesService: chapter CRUD (create/update/reorder/delete/merge), page→chapter assignment, reorder_pages, chapter-aware set_cover; list_pages now returns chapters[] + gaps[] alongside a back-compat flat pages[]. Legacy series-wide reorder operates on the single default chapter and rejects multi-chapter series. - API: chapter endpoints under /api/series/<tag>/chapters; POST pages accepts an optional chapter_id. - TagService.merge now repoints series_chapter too, so a merged series' chapters (and their pages) survive the source tag's deletion instead of cascading away. - Tests: new chapter suite; updated the 4 direct SeriesPage(...) constructions to supply chapter_id. Frontend (chapter-aware manage view + reader) lands next; until then the existing UI keeps working via the flat pages[] + single default chapter.
