feat(aiPlatformConfiguration): add contextMemory tuning block (#27455)

* feat(aiPlatformConfiguration): add contextMemory tuning block

Expose T0 user-preference memory retrieval limits (tokenBudget, maxItems)
via aiPlatformConfiguration.contextMemory so deployments can tune the
block that Collate ships to the AI Platform via the gRPC
user_memory_context field without code changes.

Both fields default to the values previously hard-coded in Collate's
ContextMemoryRetrievalService (500 tokens, 5 items), so existing
deployments behave identically.
