8.20.0 - Permission export improvements

What's new

More reliable permission exports

Permission manager downloads had a few rough edges when exporting large permission sets. Exports are now more reliable, with fewer failures on large permission sets.

CSV fallback for permission exports

Added CSV as a new export option in the permission manager. If XLSX generation struggles with a large export, CSV gives you a reliable fallback.

Real error messages on export failure

If an export fails, you now see an error message explaining that it failed instead of the download silently doing nothing.
