Resolves conflicts for PR #510 (base: beta):
- package.json: keep protospack ^3.40.0-beta.20 (carries CDC→Iceberg fields);
package-lock.json reconciled (protospack was the only dep delta vs beta).
- connection-test controller/service/dto: keep BOTH feature sets — our CDC
prerequisites validation AND beta's refresh-catalog endpoints.
- Adopt beta's cache-first catalog reads (connections-api proxy) over our gRPC
path. connectionTestListTables now enriches each table with primary_keys
derived from the cached columns endpoint (is_primary_key), preserving the
CDC create flow's need for PKs under the new architecture; spec updated.
- docsfera.json resolved to ours; regenerated on next app bootstrap.
connection-test spec: 6 passed. tsc --noEmit: clean.
