feat(form-error-ux): adopt useFormScrollToError + FormErrorSummary across remaining 10 forms

Completes the form-error rollout the prior session shipped on the 6
highest-impact forms (client/interest/yacht/company/berth/expense). Adds
the scroll-to-first-error wrapper + the top-of-form summary banner to:

- src/app/(auth)/login/page.tsx
- src/app/(auth)/reset-password/page.tsx
- src/app/(auth)/set-password/page.tsx
- src/app/(auth)/setup/page.tsx
- src/app/(dashboard)/[portSlug]/invoices/new/page.tsx
- src/components/berths/berth-detail-header.tsx (status-change dialog)
- src/components/companies/add-membership-dialog.tsx
- src/components/invoices/invoice-detail.tsx (record-payment form)
- src/components/reservations/berth-reserve-dialog.tsx
- src/components/yachts/yacht-transfer-dialog.tsx

Each call site: hook wraps handleSubmit, FormErrorSummary renders only
when 2+ errors fire (no visual change otherwise), and per-form `labels`
prop translates field names to human-readable strings. invoice-line-items
is a sub-form via useFormContext, so it inherits from the parent.

1471/1471 vitest, tsc clean.
