[management] Bump peer-metadata field-count guard for RemoteJobsAllowed

TestSqlStore_SavePeer reflects over every field of PeerSystemMeta via
PopulateAll and asserts the count, so that a newly added metadata field
forces the author to confirm it round-trips through the store. This PR
added Flags.RemoteJobsAllowed (a value bool inside the JSON-serialized
Flags), taking the recursive leaf count from 32 to 33. The field does
round-trip via the existing Flags JSON serializer, so update the expected
count. Fixes the deterministic Management/Unit store failure on all
backends.
