Consolidate the incremental goose migrations (00001-00014) into one
baseline. There is no production data, so the squash carries no data
migration. The baseline was generated from the end-state schema and
verified schema-identical to the squashed set (pg_dump diff) plus a full
integration run; the default house ad-campaign seed is carried over (a
schema-only dump omits it). The per-feature narrative that lived in the
squashed migrations is preserved in git history and docs/ARCHITECTURE.md.
Deploy note: this breaks goose's version continuity, so the test contour
DB must be wiped once — DROP SCHEMA backend CASCADE + restart backend —
for goose to re-apply the single baseline fresh. No prod data exists.
