mgr/dashboard: Set max subsystem count to 512 rather than 4096

Fixes https://tracker.ceph.com/issues/73867

- regression from https://github.com/ceph/ceph/pull/64477/files
- removing frontend valdations as this values are volatiel and require changes every release. Nvmeof is seeting these and validating as well.
