Force limit of v1 Safes for owner endpoint

- v2 paginated version is available already.
- This endpoint can take a long time and use a lot of resources for owners with a lot of Safes.
- Instead of deprecating it, a sane limit will only affect a small percentage of users, but will prevent issues on the service.
