feat: Add configurable max height for TriggerWord Toggle node

- Add new setting 'loramanager.trigger_word_max_height' (150-600px, default 300px)
- Add getTriggerWordMaxHeight() getter to retrieve setting value
- Update tags_widget to respect max height limit with scrollbar
- Add getMaxHeight callback for ComfyUI layout system
- Add tooltip note about requiring page reload

Fixes #706
