Adds a test verifying that the Value property on a delta response is typed as the concrete Application class, not the base DirectoryObject. This guards against regressions where the value items type could be resolved to an ancestor class instead of the declared schema type. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

… to index nodes
Add two tests to verify that simple path segments and OData action paths
that are siblings of index nodes (e.g., `{team-id}`, `{chatMessage-id}`)
correctly generate RequestBuilder navigation properties.
These tests document expected behavior for path patterns like:
- `/admin/teams/telephoneNumberManagement` alongside `/admin/teams/{team-id}`
- `/chats/{chat-id}/messages/replyWithQuote` alongside `/chats/{chat-id}/messages/{chatMessage-id}`

Root Cause
GetDiscriminatorMappings in OpenApiSchemaExtensions.cs, when lookupKeyInParentMapping = true (set for oneOf/anyOf members), only looked one level up in the allOf chain for a discriminator mapping:
For a 3-level hierarchy like application → directoryObject (no discriminator) → entity (has discriminator):
It looked at directoryObject → no discriminator → returned null
Fell back to GetAllInheritanceSchemaReferences, returning "microsoft.graph.application" (plain schema name, without
#)
The factory key "microsoft.graph.application" never matched the actual OData @odata.type value
"#microsoft.graph.application" → factory fell back to DirectoryObject
validate with a generation run for all languages
run with 1.30, latest main, and fix branch
Fix
Added FindAncestorSchemaWithDiscriminatorMapping() which recursively traverses the entire allOf ancestry chain to find
the first ancestor with a discriminator mapping. The lookupKeyInParentMapping block now uses this instead of the
single-level lookup, so entity's discriminator (with the correct "#microsoft.graph.application" key) is found even
when directoryObject sits between application and entity.
