fix: always initialise transcendence and apotheosis in game state

Adds INITIAL_TRANSCENDENCE and INITIAL_APOTHEOSIS constants and includes
both in INITIAL_GAME_STATE so every save document contains these fields
from the very first write, rather than only appearing post-transcendence
or post-apotheosis.
