/**
 * The commercial half of the funnel, end to end, against the live database.
 *
 *   pnpm services:up && pnpm db:migrate && pnpm db:seed
 *
 * quote → accept → booking → done → confirm → review. Until this existed the
 * chain stopped at "two people are talking": `quotes`, `bookings` and `reviews`
 * had tables and state machines and nothing that wrote a row, so `reviews` was
 * unreachable and `completed_jobs` could never move.
 *
 * The tests are ordered because the lifecycle is. Each `describe` leaves the
 * fixture one step further along, which is also the cheapest way to prove the
 * steps compose rather than merely each working from a hand-built row.
