Split gamemode winner into base group

Parse the winning gamemode string into a base group and extra subgroup before processing. The code now calls SplitGamemodeString and copies the base group into g_sVoteGameMode, and uses baseGroup for MMC_FindGameModeIndex, HasSubGroups checks, and StartCooldown calls. This prevents subgroup suffixes from interfering with game-mode lookups and vote/cooldown logic.
