ci(dev-call): add Dev Call labeled items section with label cleanup

Fetch all open issues and PRs labeled "Dev Call" and include them as a
dedicated agenda section. After a successful Discourse post, remove the
label from each item and leave a comment linking to the agenda topic.

Also adds a dry_run workflow_dispatch input (default: false) to allow
safe piloting — all fetch and build steps run normally but Discourse
posting and label cleanup are skipped.
