Refactor translation settings and prompts

- Updated paths for translation settings in backend.spec and backend_cuda.spec to reflect new directory structure.
- Renamed loadPromptConfig to loadTranslatePromptConfig in translation utility files for consistency.
- Created new YAML files for translation prompts (gemini, groq, lmstudio, ollama, openai, openrouter, plamo) with standardized system prompts.
- Added languages.yml file to define language mappings for various translation backends.
