fix: rename mage_1/cleric_1 upgrades to match adventurer IDs

The Apprentice Mage upgrade was named mage_1 and the Acolyte upgrade
was named cleric_1 — both referencing the adventurer class rather
than the adventurer ID. All other adventurer upgrades use the
adventurer ID as the prefix. Updated upgrades.ts, quests.ts (reward
targetIds), and codex.ts (sourceIds) consistently.

Closes #105
