fix(item-form): update tag handling to support key-value pairs

- Changed `tags` signal type from `Vec<String>` to `Vec<(String, String)>` for richer data representation.
- Updated `on_submit` callback to align with the new `tags` structure.
- Modified form submission logic to accommodate changes in tag handling.
