LegalText import improvements

[fabstei]

The current workaround to import the legal texts will be removed once the consultation procedure drafts are available via API. We expect an update by late April

• Whitespace regex matches

  • Use implode('\s*', str_split('$$-seal')); instead of \s

• Too eager roman divider #19

• Endpoint error when importing legacy documents #20

• Artifacts

  • Vorentwurf
  • Page numbers: sometimes there is just the page number, like "1", so there is no good pattern
  • Footnotes: difficult because we don't get the ^marker
  • YYYY- at the beginning of the file

• During import

  • control and set tags
  • check and set human title

• Add importedBy / createdBy

• Check relation to ExternalStatement (latter should work independently)

To make special characters invisible, use, e.g., json_encode($legalText);
