Add localization support and translation script
- Introduced a new extension for localization in Flutter with `LocalizationExtension` in `l10n.dart`. - Added a Python script `translate.py` for translating ARB/JSON localization files using a local Ollama model, preserving keys and placeholders, and handling ICU format rules.
