hotfix: springfiles 500 — drop springname=*&logical=or, just category=map

The previous query used springname=*&logical=or which UNION'd all categories
(maps + games + engines = ~6400 entries) and exceeded the server's response
cap somewhere around 4200 entries — every limit value above that got a 500
back. This broke SynchronizeMapsFromSpringFiles in production.

Plain category=map filters server-side to maps only (~3570 today), so any
sane limit works. Set to 100000 for headroom.
