game_data: load_weapons catches variant-schema weapons

The player's Delta Saber missile / special weapons (Weapon_DSaber_P_wep_*)
live in variant schemas (439b1f29, 28295901), not the main WEAPON schema,
so the schema-only filter missed 10 of them. Match all `Weapon`-shaped
records by table name instead (excluding the EnumWeapon name lists),
deduped by id: 121 → 131 weapons.
