FTB Quests Translator

### Added

- DeepL API Provider: You can now select `DEEPL` as your translation provider and use a DeepL API key in configs. This provides drastically better, context-aware translations.

- Contextual Formatted Translation: Entirely rewrote the formatted text translation logic (`TextFormatUtils`). Instead of breaking down sentences into chunked format codes (which destroyed the grammatical context), the mod now securely masks Minecraft codes and FTB tags into XML tags (`<mX/>`) before sending them.

- Universal Tag Protection: FTB Quests macros such as `{@pagebreak}` and `{image: ...}` handles are now perfectly shielded and treated as regular colors during translation, preventing them from being mistakenly translated and broken mid-sentence.
