fix: Add agent.kagenti.dev RBAC permissions to kagenti-ui

- Grants kagenti-ui permissions to create/manage Agent CRs
- Adds permissions for agents, agentbuilds, and agentcards resources
- Fixes "Agent 'weather-service' not found" error during import

Without these permissions, the UI cannot create or query Agent CRs,
causing agent import failures.
