ci: fix worker container list — match current infra (5 containers)

Pipeline #47 was the first green build since the infra was simplified
on 2026-05-22 (commit 66ca8b9e in infra), which removed news-fetcher,
sentiment-analyzer, trade-executor and added meet-kevin-watcher; a
later commit added kevin-signal-bridge for Phase 1. The .woodpecker.yml
patch list was never updated, so update-deployment added 3 stale
containers to the running pod (news-fetcher, sentiment-analyzer,
trade-executor) — sentiment + trade-executor crash on port 8000 since
news-fetcher binds it first.

Update the strategic-merge patch to match infra exactly:
  - signal-generator
  - learning-engine
  - market-data
  - meet-kevin-watcher    (was unmanaged → image stuck on :latest)
  - kevin-signal-bridge   (was unmanaged → image stuck on :latest)

Strategic merge doesn't remove containers not in the patch, so the 3
stale containers in the live deployment will be cleaned up by a
follow-up terragrunt apply on infra/stacks/trading-bot.
