Allow multilingual search in autocomplete

- Remove lang parameter from Photon API in geocodeSuggestions
- Users can now search in any language (English, Greek, Turkish, etc.)
- Language search is no longer restricted by current UI language
- Examples: search "Nicosia" while UI is in Greek, or "Λευκωσία" while in English
