_normalizeNode:
- Maps cpu_usage, mem_used_mb/mem_total_mb from actual API fields
- Reads capabilities.gpus: name, memory_mb, device, bound status
(bound = nvidia-smi confirmed driver, detected by name+memory_mb)
- Reads capabilities.blackmagic + blackmagic_model: model, port count,
device paths
Node detail panel:
- GPUs: name, VRAM, device path, BOUND/UNBOUND badge (green if driver active)
- Capture cards: model name, port count badge, per-port device name
with online/offline color coding
Stat row: adds Capture ports total count card
Topology SVG: shows GPU count and BMD port count under each node label
Fix: removeNode uses node.dbId (UUID) not node.id (hostname)
