This pull request updates the napari plugin GUI to explicitly display units for voxel size parameters and adds helpful tooltips.

What was done

• The labels for the x, y, and z voxel size input fields in the napari plugin were updated to include the unit "um".
• Tooltips were added to the x, y, and z voxel size parameters, providing detailed descriptions of the unit (micrometers).
• Modifications were made to the brainreg_register function in brainreg/napari/register.py to achieve these UI enhancements.

Impact

• Users will now see clear unit specifications (um) alongside the voxel size input fields in the napari plugin, enhancing usability and reducing ambiguity.
• The addition of tooltips provides immediate context and guidance to users, improving the overall user experience of the plugin.
• No breaking changes or performance impacts are introduced.

Technical details

• The file brainreg/napari/register.py was modified.
• Specifically, the label and tooltip dictionary properties for the z_pixel_um, y_pixel_um, and x_pixel_um parameters within the brainreg_register function were updated.
• These changes directly affect the presentation of the parameters in the magicgui-generated napari widget.
