refactor(ui): integrate centralized layout and display logic

Update UI components and view layout to use the new centralized layout and
display logic.

- Update `CategoryPanel` to remove redundant title text.
- Update `ViewPanel` to remove redundant title text.
- Refactor `Effect` implementations to use `display_value` and `Rc` for
  records.
- Update `GridWidget` to use the centralized `layout` and `display_text` .
- Refactor `GridLayout` to support synthetic keys for records mode and
  unified display.
- Update `view` module to re-export `synthetic_record_info` .
