feat(berths,seed): polish detail display + prune ports to Port Nimara + Amador

Berth detail (src/components/berths/berth-tabs.tsx):
- Numeric display polish, exposed by the new NocoDB-sourced seed:
  - Power capacity now renders with kW unit (e.g. "330 kW")
  - Voltage now renders with V unit (e.g. "480 V")
  - All metric/imperial values rounded to <= 2 decimals
    (was: "62.999112 m" -> now: "62.99 m")
  - Nominal Boat Size shows full ft + m pair (was: ft only)

Seed ports (src/lib/db/seed.ts):
- Drop Marina Azzurra and Harbor Royale; install now seeds only:
  - Port Nimara  (the real install)
  - Port Amador  (secondary, for multi-tenant isolation tests / Panama
                  scaffolding)
- Existing dev DBs are not touched; this only affects fresh `pnpm db:seed`
  runs. Users wanting to migrate should drop existing rows in the obsolete
  ports manually before re-seeding.

Verification:
- lint clean, tsc unchanged from baseline (36 pre-existing errors), 858/858
  vitest passing.
