Server folders encode the game and map (e.g. t5_ascension_1 = game t5, map
alias ascension, lobby 1). A T5_MAP_ALIASES table translates the friendly
alias to the canonical mapname RCON reports (ascension → zombie_cosmodrome),
covering every base + Rezurrection map. seedServerRegistry now populates
game and map at insert time and backfills existing NULL rows on every boot;
unknown aliases log a warning so we know when to add them.
