Subject: [PATCH] Fix agent name population + Manage tab linked agent detection

- link-agent API: accept agentName/agentDescription/agentGenre from
  request body as fallback when RPC metadata lookup fails
- agents page: check linked_agent_wallet on human user row to detect
  linked OWS agent, show in Manage tab (#991)
