feat(deps): @faker-js/faker wide-synthetic seed for load testing

New seed harness for stress-testing list pages, search, analytics
under realistic volumes. Faker-driven, deterministic via fixed
seed, idempotent via `clients.source_details = 'wide-synthetic'`
marker.

- `src/lib/db/seed-wide-synthetic-data.ts` — generator (1000 clients
  default, override via `WIDE_SEED_COUNT`)
- `src/lib/db/seed-wide-synthetic.ts` — entrypoint
- `pnpm db:seed:wide-synthetic` script

Distribution:
- 70% of clients get an interest (spread across pipeline stages)
- ~50% of those interests link to a real berth
- Acquisition source weighted: 55% website / 25% referral /
  15% broker / 5% manual
- Locale-aware names/emails/phones/addresses via faker

Curated synthetic seed (`seed-synthetic-data.ts`) and realistic
seed (`seed-data.ts`) are untouched — this is a third axis for
volume testing, not a replacement.

Verified: tsc clean, build green.
