feat(history): add Lord Ruler character and assign e_final_empire

Add Rashek (ID 900100) as the immortal god-emperor of the Final
Empire. Full Mistborn and Feruchemist with health=10 for
immortality, compounder_modifier applied at game start. Create
dynasty_rashek and house_rashek with localization. Assign
e_final_empire to the Lord Ruler in title history, resolving
REVIEW_NOTES NOTE-03. Add safety-net on_game_start effect for
compounder_modifier.
