Subject: [PATCH] fix: add created field to chapters_idx to fix
 recentlyUpdatedBooks 400
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

chapters_idx was missing created/updated columns (never defined in the
PocketBase schema), causing PocketBase to return 400 for any query
sorted by -created. recentlyUpdatedBooks() uses this sort.

- Add created date field to chapters_idx schema in pb-init-v3.sh
  (also added via add_field for existing installations)
- Add idx_chapters_idx_created index for sort performance
- Set created timestamp on first insert in upsertChapterIdx so new
  chapters are immediately sortable; existing records retain empty created
  and will sort to the back (acceptable — only affects home page recency)
