Example-flows + noder: defaults pekar bara på filer som finns

Flöden (flows/example-flows.json):
- Kedjor som skapar det de behöver: png→asset, templates:list→create→
  extract/fill/transform/extractFields, create A+B→compareVersionsPdf
- Defaults /Dokument/Example.md, /Dokument/exempel.odt, dest
  /Dokument/OfficeOut/, mall-id 230 (Invoice.odt via templates:list)
- Ingen referens till /Mallar/avtal.docx, avtal-ny.docx eller logotyp.png
- Debug-noder med tostatus=false (undviker TypeError-length i status)

Noder:
- nc-office templates:create: skickar path+template (richdocuments-
  kontrakt), ärver extension från mallen, MKCOL av mapp, idempotent
  (återanvänd existerande fil i stället för 'namn (2)') — fixar OCS 400
- nc-office document:direct: fileId camelCase (+fileid), 996-fel
  inkluderar nu OCS-body i felmeddelandet
- collabora-wopi discovery: rewrite urlsrc/favIconUrl till
  collaboraPublicUrl så iframe inte går mot CODE bridge-IP
- webdavGet/PROPFIND 404: feltext med föreslagen åtgärd
- resolveDestNcPath: tvingar rätt filändelse (.pdf/.png/…)
- Nytt: listUserExamples (PROPFIND /Dokument+/Documents) +
  bridge-op pickDemoSource; scripts/discover-examples.js

Verifierat mot cloud.domain.name (your-user): capabilities, discovery-
rewrite, pdf/png, asset-länk, mall-skapa+extract/fill/transform,
compare A/B→pdf, document:direct, htmlToOffice — ALL PASS.
