chore(dump): refresh static API for the 29 merged laptop records

Regenerated the static laptop dump from the deduped dataset (python -m app.dump
against a fresh scratch database seeded from this worktree). Drops the 29
orphaned per-slug pages for the removed duplicates and updates the laptop
collection count in the list and manifest (1995 -> 1966). Scope limited to the
laptop collection touched by this change.
