Durable curation: persisted splits + pre-resolve title edits, catalog A→Z

Wiz-War had no split button: can_split required a matches row, but fresh
extractions leave multi-photo titles rowless until resolve runs. Splits
are now a title-level decision persisted in data/title_splits.json,
honored by extract's dedupe and resolve's dedupe on every rebuild, with
the button on any multi-photo line — resolved or not.

Same mechanism carries human corrections: data/title_edits.json stores
fixed misreads and known cues (publisher/edition/year/language), applied
before dedupe on every titles.json rebuild, editable from a new inline
form on every catalog line. An edit drops the title's stale matches rows
so resolve re-queries with the corrected data.

The catalog page now sorts alphabetically (case-insensitive; split
copies stay adjacent) instead of extraction order.
