LibreOffice Writer has no CSV export filter. The shared filter map used
Text for csv in both directions, which made any Writer-category conversion
to csv fail with:
no export filter for <file>.csv found, aborting.
Root cause: getFilters() looked up the same filters map for the infilter and
the outfilter. Text is a valid *input* filter for reading delimiter-
separated files in Writer but is not accepted as an *output* filter for the
.csv extension.
Fix:
- Split into separate inputFilters / outputFilters maps so csv can remain
readable by the text (Writer) category without offering it as a write
target there.
- Remove csv from properties.to.text so the UI/router no longer exposes
the unsupported Writer → CSV path.
- Populate the previously-empty filters.calc with correct LibreOffice Calc
filter names and add spreadsheet formats to properties.from.calc /
properties.to.calc, enabling conversions such as xlsx → csv, csv → xlsx,
ods → xlsx, etc. via the Calc module.
