Split seed into orchestrator (seed.ts) + per-port fixture builder
(seed-data.ts). Creates three ports (Port Nimara, Marina Azzurra,
Harbor Royale) and seeds each with a realistic multi-cardinality
dataset: 12 berths (5 available / 5 reserved / 2 sold), 8 clients
with contacts and primary addresses, 3 companies (2 active / 1
dissolved) with billing addresses, memberships exercising dual-
company ownership and ended state, 12 yachts (7 client-owned /
5 company-owned) plus matching open ownership-history rows, 3
completed ownership transfers per port (client <-> company), 15
interests spanning all pipeline stages, and 8 reservations (5
active on distinct berths / 2 ended / 1 cancelled). Seed wraps
per-port work in withTransaction and is idempotent: re-running
detects existing company rows and skips.
