fix(server-test): fix pgvector and _meta test failures in CLI e2e

- pgvector test: vector arrays can't be passed via CLI dot-notation
  (they become strings, not JSON arrays). Changed test to verify the
  CLI reports a clear GraphQL type error rather than crashing silently.
- _meta test: replaced with schema introspection test since the
  search-seed server doesn't load MetaSchemaPlugin (enableServicesApi
  is false). New test verifies Article type exposes expected search
  fields (tsvRank, titleTrgmSimilarity, bodyTrgmSimilarity, searchScore,
  and conditionally pgvector fields).
