feat(trigger_word_toggle): refactor trigger word filtering logic, fixes #718 and fixes #285

- Simplify and consolidate the logic for processing trigger words and groups
- Remove redundant code paths and improve maintainability
- Ensure consistent behavior between list and string trigger data inputs
- Preserve existing functionality for strength adjustment and group mode
