Omni's Custom Items 1.0.86 rendering fix

- Preserves the confirmed-correct placed Gilded Boar Feast.
- Routes only Aetherwild Game, Gilded Boar Feast, Homey Heart Haunch, and Fig-Crowned Braised Rabbit inventory/handheld models through their exact authored meshes.
- Leaves all mesh, texture, blockstate, item-display, recipe, effect, and registration assets unchanged from 1.0.53.
