feat: clear partial masked input on blur

Implemented logic to reset value if replacement characters remain on blur, ensuring data integrity. Resolved TODOs regarding blur dispatch and value clearing. Practical example: The field is a date field `__/__/__`, the user types to make the field display `12/__/__ `. The field's internal `value` will be reset to `""` (the field will display `__/__/__`) when they click off, to ensure input integrity.
