Consolidate service scripts into apps directories

- Move blockchain scripts to apps/blockchain-node/scripts/
- Move marketplace scripts to apps/marketplace/scripts/
- Move agent daemon to apps/agent-coordinator/scripts/
- Move monitor to apps/monitor/
- Update systemd service files to point to new locations
- Update internal path references in moved scripts
- Remove empty /opt/aitbc/services directory
