fix(cicd): allow skipped Deploy-to-Morpheus-P-Node to satisfy C-Node deploy needs

Root cause of the first v7 test-branch run (GH Actions run 24796856145):
the drain job ran and deregistered the dev C-Node from both NLB target
groups, then Deploy-to-Morpheus-C-Node was silently skipped because its
implicit success() guard propagated the skip from Deploy-to-Morpheus-P-Node
(which is main-only and intentionally skips on test pushes). That left
dev with the old C-Node task running in ECS but with no load-balancer
membership until we manually re-registered it.

Fix:

- Add an explicit `if` to Deploy-to-Morpheus-C-Node that:
  - Requires GHCR build + drain success.
  - Accepts Deploy-to-Morpheus-P-Node.result in {success, skipped}.
  - Wraps in `!cancelled()` so manual cancels still short-circuit.
- Rewrite the inline comment that previously (incorrectly) claimed
  skipped jobs are treated as successful for dependency resolution;
  they are not.

No change to the deploy logic itself, the drain job, or any other
workflow sequencing. This is a pure `needs` / guard correctness fix.
