fix agent templates to displace all knowledge bases

[yashoza19]

Pull Request

Description

This commit resolves two issues preventing knowledge bases from being properly linked to agents created from templates:

Problem 1: Incorrect field used for knowledge base IDs

• Previously used 'name' field (display name like "Commercial Banking Reference")
• Now correctly uses 'vector_store_name' (LlamaStack identifier like "commercial_banking_kb")

Problem 2: Timing issue with asynchronous ingestion pipeline

• Agent creation validated KB existence in LlamaStack immediately
• But ingestion pipeline creates vector stores asynchronously (takes time)
• Solution: Skip validation for newly created KBs via new skip_kb_validation parameter

The ingestion pipeline still needs to be fixed, @olavtar will open a PR to fix the ingestion pipeline chart version to 0.5.0 after this is merged in.
