fix(ci): make iOS TestFlight non-blocking for desktop release pipeline

The iOS TestFlight job fails when IOS_CERTIFICATE_P12 secret is not
configured. Previously this blocked the entire release pipeline including
desktop builds, CLI publish, and GitHub Release creation.

Add `if: !cancelled() && ...` conditions to publish_cli, release, and
finalize jobs so they proceed when iOS signing secrets are unavailable.
