feat: add multilingual support for OBF and Asterics grid files

- Update `BaseProcessor.processTexts` to accept `targetLocale` for adding languages
- Implement multilingual writing support in `ObfProcessor` (updating `strings` dictionary)
- Implement multilingual writing support in `AstericsGridProcessor` (updating `label` maps)
- Ensure `ObfProcessor` correctly resolves strings based on locale during load
- Add comprehensive tests for multilingual workflows
