fix(geoportal-v2): disable Ortofoto ANCPI button in PIZ modal

gis-api currently returns 501 basemap_not_supported for basemap='orto'
(needs orchestrator-side basemap endpoint that proxies the eTerra account
pool — not yet wired). Showing a clickable button that errors out is bad
UX; gate it with a dashed style + 'curând' badge + tooltip explaining
the dependency so the user reaches for Google Satellite (default,
fully working) instead.

Re-enable when orchestrator ships the basemap endpoint.
