feat(import): render the file import in a GeoImport view

The file import no longer looks up or listens on the Import button, the
picker or the list, and no longer restores focus itself. It connects
importGeoFiles, toggleGeoImport, flyToGeoImport and removeGeoImport to
the display store. A new GeoImport view owns the button, the picker, the
rows and the hint: it opens the picker once the import has presented
itself, sends the pick and the row buttons' actions, and hands keyboard
focus on with v-focus-safe-children before a focused row goes, to the
next row's same button, else the previous row's, else Import.
