Integrate nostr into everything: remove ordinals, stacks, and NFT badess from mesh, infrastructure, and workforce

Nostr replaces:
- Ordinals/Stacks -> Nostr relay chains for identity and records
- Bitcoin DIDs -> Nostr DIDs (pubkey-based)
- NFT-based badges -> Attestation server-issued credentials (not NFTs)
- On-chain attestation -> Nostr NIP-based peer verification
- Property registry -> Nostr-anchored on Bitcoin
- Governance voting -> Bitcoin via Nostr relay chains
- Governance records -> Relay-anchored on Bitcoin mesh

NFTZ token name preserved as network token (not NFT references)
