feedback::InlineMessage lays its words in a block that wraps, so the
importer's reason for unread text no longer runs past the dialog. The
reader skips a leading byte order mark, names the line an unclosed
quote opened on, and logs once per reading. Tests press each Cancel,
the scrim, Export with the first format, see focus return to the
opener, read new text under an open importer, and see a field with no
column come empty.
misc::ExportDialog offers the owner's formats as cards and hands the
chosen one over for the owner to write. misc::ImportDialog maps the
file's columns to the app's fields, matched by name to start, over a
preview, and asks for each required field's column. misc::CsvImporter
reads CSV as RFC 4180, lets the first row name the columns or not, and
maps it through the ImportDialog into records; text that does not read
says why.
