v0.4.107 - Surface DCAT-AP fields in package_show

What's New

Improvements

• ckan_package_show now surfaces DCAT-AP metadata fields that the CKAN API already returns but the markdown output previously hid:
  • Rights Holder (dct:rightsHolder)
  • Publisher (dct:publisher)
  • Update Frequency (dct:accrualPeriodicity)
  • Language (dct:language)
  • Access Rights (dct:accessRights)
• Holder/Publisher resolved via the existing readDcatExtra logic (extras override root on aggregator catalogs), keeping search scoring and dataset detail consistent.

Notes

• conforms_to intentionally excluded (renders as raw JSON on some portals).
• Verified on dati.gov.it (DCAT-AP-IT) and open.canada.ca (no regression).

No Breaking Changes

• All existing functionality preserved.
