Enhance AutoMod functionality with default word list and improved filtering

- Introduced a default blocked words list for the WORD_FILTER, including common profanity in both English and German.
- Updated the word matching logic to utilize Unicode word boundaries, reducing false positives.
- Implemented a button in the WebUI to load the default word list, enhancing user experience.
- Added functionality to seed default word filters only when necessary, preventing overwriting user-defined lists.
- Improved localization for new features related to the word list in both English and German.
- Documented changes in phase tracking to reflect the new AutoMod enhancements.
