fix(geoportal): layer toggle + enrichment update + refresh button

1. Layer toggle fix: removed isStyleLoaded() check that silently blocked
   visibility changes when OpenFreeMap style has pending sprite/font loads
2. Enrichment: "Actualizeaza" button always visible (re-fetch from eTerra)
   replaces "Enrichment" button when data already exists
3. Panel updates with returned enrichment data immediately
