The config-sync sidecar intentionally leaves www/ to HACS, but
www/heizungsanlage-card.js is a bespoke, non-HACS custom card committed to the
HA config repo (k.renner/homeassistant). Add that exact path to PATHS so the
sidecar force-syncs just that one file into /config/www; the rest of www/ stays
HACS-managed.
Note: extra_module_url is read only at HA startup, so a one-time full restart is
still needed to load the card after the file first lands.
