fix(trigger-words): auto-commit pending input on save/blur to prevent data loss, see #785

- Auto-commit input value when clicking save button
- Auto-commit on blur to handle users clicking outside input
- Fixes issue where users would type a trigger word and click save,
  but the word wasn't added because they didn't press Enter first
- Maintains backward compatibility with existing comma-based workflows
