fix: Resolve 4 pipeline runtime issues for full phase execution

1. Trivy/Checkov disk space: Set TMPDIR=/var/tmp in Dockerfile, ensure
   /var/tmp has 1777 permissions for large temp files (DB downloads)
2. Fuzzing: Fix method mismatch scanner.scan() -> scanner.fuzz_function()
   with Python file discovery and crash-to-finding conversion
3. Runtime Security: Fix monitor.monitor() -> monitor.monitor_realtime()
   with ThreatAlert-to-HybridFinding conversion
4. DAST: Auto-discover OpenAPI/Swagger specs when no --dast-target-url
   provided, search target dir for openapi.json/swagger.yaml patterns
5. Docker socket: Add docker group (GID 999) to agentuser for sandbox
   validation access
