feat: add network.status dashboard action (108 total)

One-call network overview for external humans:
- chain: height, difficulty, hashrate, hf5 status
- network: aliases, gateways, services, pools, capability counts
- economics: block reward, total supply, fee, emission model

Total Core Actions: 108.
