feat(i18n): country/phone/timezone/subdivision primitives + form wiring

Cross-cutting i18n polish for forms across the marina + residential + company
domains. Introduces a single source of truth for country/phone/timezone/
subdivision data and replaces every nationality-as-free-text and timezone-
as-string Input with a dedicated combobox.

PR1  Countries — ALL_COUNTRY_CODES (~250 ISO-3166-1 alpha-2), Intl.DisplayNames
     for localized labels, detectDefaultCountry() with navigator-region
     fallback to US, CountryCombobox with regional-indicator flag glyphs +
     compact mode for inline use.
PR2  Phone — libphonenumber-js wrapper (parsePhone / formatAsYouType /
     callingCodeFor), PhoneInput with flag dropdown + national-format
     AsYouType + paste-detect that flips the country dropdown for pasted
     international strings.
PR3  Timezones — country->IANA map (250 entries, multi-zone for AU/BR/CA/CD/
     ID/KZ/MN/MX/RU/US), formatTimezoneLabel ("Europe/London (UTC+1)"),
     TimezoneCombobox with Suggested/All grouping driven by countryHint.
PR4  Subdivisions — wraps the iso-3166-2 npm package (~5000 ISO 3166-2
     codes for every country), per-country cache, SubdivisionCombobox with
     "Pick a country first" / "No regions available" empty states.
PR5  Schema deltas (migration 0015) — clients.nationality_iso, clientContacts
     {value_e164, value_country}, clientAddresses {country_iso, subdivision_iso},
     residentialClients {phone_e164, phone_country, nationality_iso, timezone,
     place_of_residence_country_iso, subdivision_iso}, companies {incorporation_
     country_iso, incorporation_subdivision_iso}, companyAddresses {country_iso,
     subdivision_iso}. Plus shared zod validators (validators/i18n.ts) used
     by every entity validator + route handler.
PR6  ClientForm + ClientDetail — CountryCombobox replaces nationality Input,
     TimezoneCombobox replaces timezone Input (driven by nationalityIso hint),
     PhoneInput conditionally rendered for phone/whatsapp contacts. Inline
     editors (InlineCountryField / InlineTimezoneField / InlinePhoneField)
     for the detail-page overview rows + ContactsEditor.
PR7  Residential client form + detail — phone -> PhoneInput, nationality/
     timezone/place-of-residence-country/subdivision rows in both create
     sheet and inline-editable detail view. Subdivision wipes when country
     flips since codes are country-scoped.
PR8  Company form + detail — incorporation country -> CountryCombobox,
     incorporation region -> SubdivisionCombobox in both modes.
PR9  Public inquiry endpoint — accepts pre-normalized phoneE164/phoneCountry
     and i18n fields from newer website builds, server-side parsePhone()
     fallback for legacy raw-international submissions. Old Nuxt builds
     keep working unchanged.

Tests: 4 unit suites for the primitives (25 tests), 1 integration spec for
the public phone-normalization path (3 tests), 1 smoke spec asserting the
combobox triggers render in all three create sheets.

Test totals: vitest 713 -> 741 (+28).
