fix: move peasant_1 and militia_1 upgrades to earlier quests (#111, #112)

peasant_1: moved from storm_citadel (zone 3, 1.5M CP) to goblin_camp
(zone 1, no CP gate) — the starting adventurer's upgrade should be
available from the very early game.

militia_1: moved from shadow_mere (zone 4, 5M CP) to necromancer_tower
(zone 2, 500 CP) — tier 2 adventurer upgrade should unlock soon after
the adventurer itself.
