dinhkarate 36efcc6e28 fix(vertex): include prefix in auth filename and validate at import
Address two blocking issues from PR review:
- Auth file now named vertex-{prefix}-{project}.json so importing the
  same project with different prefixes no longer overwrites credentials
- Prefix containing "/" is rejected at import time instead of being
  silently ignored at runtime
- Add prefix to in-memory metadata map for consistency
