feat(i18n): add portuguese (pt-br) locale

Adds a new 'pt' language with locale 'pt-BR' alongside the existing
en, sv, de, fr and es locales.

- New translation file src/app/i18n/messages/pt.ts (1196 keys, full parity with en.ts)
- Register 'pt' in SUPPORTED_LANGUAGES, LANGUAGE_OPTIONS, LOCALE_BY_LANGUAGE
- Wire ptMessages into the MESSAGES record
- Add Portuguese boot copy to public/boot-i18n.js
