fix: convert items show for unselected files; add success toast

canRename required selectedEntityIds.size === 1, so right-clicking an
unselected file hid the convert items even though contextMenuEntityId
was correctly set. Replace canRename with !fileTreeReadOnly for the
convert-specific gate, which is the actual write-access check needed.

Also add showExportDocumentSuccess so the user sees the warning toast
on successful conversion instead of silent nothing.
