[borodino] fix(bm12): replace UPDATE with UPSERT in parse_and_store_nmap_xml

Commit 8b74797

Description

• INSERT … ON CONFLICT DO UPDATE (upsert) instead of bare UPDATE → services now created if absent, not just updated
• Recalculate service_count after each nmap scan
• Root cause of 0 services imported: nmap unreachable via ProtonVPN (wg-gateway blocks raw SYN scans) — separate network issue
