Feat: Kodeliste fra lovdata

Hente ut liste over lover (i ELI-format) fra lovdata-api (list/base)

Eksempel på lov-objekt:
{
"iD": "NL/lov/2026-06-23-73",
"legacyID": "LOV-2026-06-23-73",
"lastModified": "2026-06-23T12:40:37.439Z",
"filenameHTML": "nl-20260623-073.html",
"changes": [],
"datePromulgated": "2026-06-23T09:55:00.000Z",
"title": "Lov om endringer i straffeprosessloven",
"shortTitle": "Endringslov til straffeprosessloven",
"ministry": "Justis- og beredskapsdepartementet",
"lastHistoricVersion": "2026-06-23",
"eliURI": "/eli/lov/2026/06/23/73"
},

for øyeblikket har objektet kun eli-uri, forhåpentligvis er Lovdata villige til å dele hele eli-objektet

Start by locating the Java integration with the Lovdata API and the list/base endpoint mentioned in the issue. Inspect how reference data is retrieved and represented, then verify that the laws list is fetched in ELI format with the available fields from the example object. Done means the requested law list can be retrieved from Lovdata and handled by the project.
