Add missing VinylDNS API endpoints

[JoshSEdwards]

Summary

• add endpoint builders and query helpers for new health/status, zones, recordsets, groups, users, and batch-review routes
• add client methods for ping/health/color/Prometheus metrics, status get/update, backend IDs, deleted zones, ACL rule add/delete, recordset count/history/failures, group change/valid domains, user get/lock/unlock, and batch review actions
• add ownership transfer helpers for record sets (request/approve/reject/cancel) that wrap record set update payloads
• add fixtures and unit tests for all new endpoints and methods
• fix SigV4 signing for GET/DELETE by omitting empty request bodies
