Native menu bar, provider status strings, export dialog, layer panel,
and image-panel popovers now resolve through op-i18n instead of
hardcoded English; the three ad-hoc mini locale tables fold into the
canonical catalogs. New *_panel.rs overflow shards keep every table
under the 800-line cap (catalog at 1098 keys). The desktop menu also
rebuilds live on locale change instead of waiting for the next launch.
Includes the pending interactions/quick-action/dialog locale entries
and locale.rs additions from the working tree.
