feat(modules/panel/components): adjust dropdown capture layer and pointer widget assignments

Changed the default layer used by `create_dropdown_with_capture` from `"bottom"` to `"top"` and updated the call site accordingly. Added safety checks to set `_pointing_widget` on indicator windows when they exist, preventing potential errors when the windows are not created.

- Enhancements:
  - Updated default `layer` parameter in `create_dropdown_with_capture` to `"top"`.
- Bug Fixes:
  - Ensured `BluetoothIndicator`, `NetworkIndicator`, and `BatteryIndicator` properly assign `_pointing_widget` to their respective buttons when the associated windows are present.
