fix: restore upgrade drops to late-game bosses

Assigned 3 previously orphaned adventurer upgrades to appropriate bosses:
- horizon_beast (Infinite Expanse) → oblivion_paladin_1
- maelstrom_god (Cosmic Maelstrom) → transcendent_rogue_1
- eternal_end (The Absolute) → omniversal_champion_1

Closes #140
