Fix divisionRank ordering and add warning for unknown teams

Sort teams by win-loss within each division group before assigning
divisionRank so that the leader is always the best-record team, not
whichever team happened to appear first in ESPN's flat response.

Also warn to console when a team's displayName isn't in the hardcoded
MLB_TEAM_DIVISION map, surfacing renames or expansion teams immediately
instead of silently storing division="" and recreating the display bug.
