Read offering info and bane rank through the bridge

Shrine boons read getItemOfferingInfo() and the banestone and bane
production paths read getItemBaneRank() on template.cacheTemplate.

The legacy parser only kept item_bane_rank when ACTIONRESPONSE is
4250517122; the cache parsers always read it. Parity shows this makes
no difference: every template outside that gate has bane rank 0.

Parity (offline, scripts/p14.py, 7586 templates): 0 differences in
item_offering_info and item_bane_rank. No value changes expected.
