fix: consolidate KeyMeta interface and improve type safety

- Remove duplicate KeyMeta interface from crypto/vc/index.ts
- Import KeyMeta from common.ts as single source of truth
- Add missing fields to KeyMeta interface (identity, passkeyCredIdHex)
- Remove unused ErrorResponse interface from endorserServer.ts
- Fix import path for KeyMeta in crypto/vc/index.ts

This change resolves type compatibility issues and ensures consistent
KeyMeta type usage across the codebase.
