root 4715353795 fix(ci): auto-discover reachable Portainer URL from job container
CI/CD Pipeline / Build & Deploy (pull_request) Successful in 19s
The act_runner on the QNAP creates an ephemeral docker bridge per job.
That network can't always reach the canonical PORTAINER_URL
(http://192.168.1.30:9000) — first deploy run failed with
'Failed to connect to 192.168.1.30 port 9000 after 130317 ms'.

New step 0 probes several candidate URLs (container's own IPs, default
gateways, then the secret value as fallback) against /api/status and
uses the first that returns 200. The reachable host is then reused for
the DELETE+CREATE calls and the smoke-test on :3001.

# Optional redeploy step (gated by workflow_dispatch.deploy=true).
#
# Approach: delete the existing stack on Portainer (idempotent), then
# create a new one from the docker-compose.prod.yml at the repo root.
#
# We DELETE + CREATE rather than PUT-edit because:
# * Put-edit requires the same stack ID + PRUNE; the simpler recreate
# works for our size (1 service, no inter-service references).
# * Earlier the stack was "unhealthy"; this gives a clean slate.
#
# Required secrets:
# PORTAINER_URL e.g. http://192.168.1.30:9000
# PORTAINER_TOKEN Access token from a Portainer user (scope: admin)
# PORTAINER_ENDPOINT_ID Numeric endpoint ID (usually 1)
# PORTAINER_STACK_ID Numeric stack ID to delete before recreating
