worker compose: run node-agent in host network mode

Browse source 
The agent now uses network_mode: host so os.hostname() and the network
interface list reflect the actual host instead of a per-container random
hex hostname (root cause of duplicate Zampp2 rows) and a 172.x docker
bridge IP. Also passes NODE_IP and BMD_MODEL through for explicit overrides.

# Required env vars (set in .env.worker or export before running):
# MAM_API_URL URL of the primary MAM API e.g. http://10.0.0.25:47432
# NODE_TOKEN Bearer token from the primary's Tokens page
# NODE_IP Host LAN IP to report (set by onboard-node.sh)
#
# Optional hardware overrides (if Docker can't see /dev directly):
# GPU_COUNT Number of NVIDIA GPUs on this node (default: auto-detect from /dev/nvidia*)
# BMD_COUNT Number of Blackmagic DeckLink cards (default: auto-detect from /dev/blackmagic/)
# BMD_COUNT Number of Blackmagic DeckLink cards (default: auto-detect from /dev/blackmagic/)
# BMD_MODEL Marketed card name (e.g. "DeckLink Duo 2") — drives the port-diagram UI
#
# Optional env vars (needed only if starting the worker or capture profiles):
# REDIS_URL, DATABASE_URL, S3_ENDPOINT, S3_BUCKET, S3_ACCESS_KEY, S3_SECRET_KEY

# Profiles:
# (default) node-agent only — cluster visibility + hardware heartbeat
# --profile worker + CPU job worker (proxy generation, transcoding)
# --profile worker + CPU/GPU job worker (proxy generation, transcoding)
# --profile capture + SDI capture service (requires Blackmagic DeckLink card)
#
# To enable GPU transcoding, also apply docker-compose.gpu.yml:
# docker compose -f docker-compose.worker.yml -f docker-compose.gpu.yml --profile worker up -d
#
# Examples:
# # Agent only (register node in cluster, report hardware):
# docker compose -f docker-compose.worker.yml up -d
#
# # SDI capture node (1 DeckLink, no GPU worker):
# docker compose -f docker-compose.worker.yml --profile capture up -d
#
# # Full node (GPU worker + SDI capture):
# docker compose -f docker-compose.worker.yml -f docker-compose.gpu.yml \
# --profile worker --profile capture up -d
services:
# node-agent runs in host network mode so it can see the real host
# interfaces, GPU devices and DeckLink cards without bridging tricks.
# The reported IP / hostname will be the host's, not the container's.
