feat(transcribe): English UI default, language switcher (NO/UK/PL), fix 504 timeout

- Default UI language to English; lang switcher (EN/NO/UK/PL) persisted in localStorage
- Rename 'rettssak/tingrett' preset to 'Mediation / legal meeting' — court recording is illegal
- Add Ukrainian (uk) and Polish (pl) as selectable audio transcription languages
- TRANSCRIBE_I18N translation object drives all status messages, labels, and trace text
- Apache ProxyTimeout raised to 1800s on server (was 300s — caused 504 on large files)
- set_time_limit(0) + ignore_user_abort(true) in api/transcribe.php
- applyTranscribeI18n() patches data-i18n / data-i18n-placeholder / data-i18n-aria attrs
