feat: wire Neo4j adapter to GormRegistry O(M+N) scaling

[borinquenkid]

Summary

Wires the Neo4j adapter into the GormRegistry introduced in #15780.

• Neo4jGormEnhancer — registers Neo4j GORM APIs with GormRegistry via the standard factory pattern
• Updated Neo4j TCK specs and affected tests to use the registry-based API path
• Unit test: Neo4jTenantContextProfilingSpec

Test plan

• ./gradlew :grails-data-neo4j:test passes
• TCK suite passes with Neo4j datastore

Stack

• Prereq: (1/3) feat: add SessionResolver infrastructure and extend core datastore APIs #15779 → (2/3) feat: GORM O(M+N) scaling — GormRegistry, GormEnhancer, and core API refactor #15780 → test: add unit and TCK tests for GormRegistry O(M+N) scaling #15781 → feat: wire Hibernate 5 adapter to GormRegistry O(M+N) scaling #15782 → feat: wire MongoDB adapter to GormRegistry O(M+N) scaling #15783
• This PR — Neo4j wiring
• Next: feat/gorm-registry-simple

Closing as part of consolidating the GormRegistry work into #15780. Neo4j is a separate Gradle build that resolves GORM via published artifacts, so its GormRegistry wiring will be a separate follow-up once core publishes — it cannot be built/verified within this stack. Closing as superseded here; the branch is retained for reference (not deleted).
