test(ui): fix agent identity fixture typing

Regeneration-Prompt: |
  While preparing openclaw/openclaw#35474 against a moving origin/main, pnpm check started failing in ui/src/ui/views/agents-utils.test.ts because AgentIdentityResult now requires agentId and name in addition to avatar. Keep runtime code unchanged and update only the test fixture in the avatar-resolution case so it satisfies the full AgentIdentityResult shape.
