Changes

• Add Ansible playbook with user, group, file, copy, template, systemd modules
• Create systemd service template with environment variables
• Configure inventory for Vagrant VM SSH connection

Testing

• First run: changed=7, service active on :9090
• Second run: changed=0 (idempotency confirmed)

• --check --diff shows expected diff
• curl /health returns {"notes":2,"status":"ok"}
