Subject: [PATCH] viewer: settings fields fill the panel width (form growth
 policy)

The settings content stopped resizing past ~360 px, leaving dead space when the
dock was widened. Cause: QFormLayout's default field growth policy keeps fields
at their size hint. Set AllNonFixedFieldsGrow on all five forms (geometry, unit
cell, spot finding, indexing, azint) so the fields grow to fill the dock width.
