Load rune powers from item_power_grant instead of static_rune_powers

Parity (scripts/p28.py): all 1066 DB runes with a JSON file match in value
and order; token = SBStringHash(power_type), rank = power_value, name = obj_name.
The 14 Magister Captain guard contract ids (848, 952, 1052, 1182, 1252, 1352,
1452, 1502, 1527, 1552, 1557, 1602, 1652, 980102) have no rune file; guard
spells are server-made, so they keep their DB rows.
The JSON adds 170 class/discipline/talent runes; none is a mobbase, and the
trainer contracts among them never reach the guard contract path in MobAI,
so no reachable value change.
