CMSNavigationEngine..::..GetNavigationForCacheVerify Method

Single-call routing-cache verify. Wraps Route_CacheVerify()()()() (sp_CORE_Route_CacheVerify) which does both the Nav fingerprint check and the rewrite-target existence check in one round trip, then returns the same Nav projection as GetNavigationByID(Int32, Int32, Int32, ActionArgs) when both pass.

Three-state return for RoutingCache:

• null -- the SP threw (missing during a deploy/upgrade window, schema drift, transient SQL error). Caller bypasses the cache for this hit but does not evict the entry; next request retries. The cold path keeps the site live in the meantime.
• Returned Navigation with PublishedTemplateFilePath == null -- SP returned zero rows (fingerprint mismatch, Nav deleted, or rewrite target republished / unpublished / remapped). Caller evicts and falls through to the cold path.
• Returned Navigation with PublishedTemplateFilePath set -- verify passed; the Navigation is fully populated (rewrite columns included) and ready to attach to the RewriteResult.
