* Show leagues where user is a member regardless of team assignment
The homepage now uses a union query to show leagues where the user
either has a team in the current season OR is a commissioner. Previously,
commissioners without a team could not see their leagues on the homepage.

* Fix stale empty state card title in home route
Update 'No Active Leagues' to 'No Leagues' to match the updated
description which is now about membership rather than active seasons.

* Fix union import: use two queries with JS deduplication
drizzle-orm 0.36.x does not export a standalone union() function.
Replace with two awaited queries merged via a Map (dedup by id),
then sorted by createdAt descending in JS.
