Subject: [PATCH] =?UTF-8?q?fix(geoportal):=20building=20labels=20C1/C2=20?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previous index-of expression wasn't rendering. Simplified to use
filter with index-of on dash + slice from dash position.
Also lowered minzoom from 17 to 16.

Added diagnostic log in enrichment for building cross-ref count
to debug HAS_BUILDING=0 cases.
