ci: add dispatch-only kaniko-act build, targeting the org registry

Bootstrap step for moving container images off the personal namespace. Builds using the existing mikkeli/kaniko-act; the org copy is what this run produces.

+# Rebuilds the kaniko-act builder image.
+#
+# Dispatch-only on purpose. This is the image build-image.yml runs inside, so
+# an automatic trigger could push a broken builder and take the whole build
+# path down with it. Bump deliberately, verify, then repoint build-image.yml.
+#
+# Self-hosting: builds the new kaniko-act using the *previous* kaniko-act, per
+# the bootstrap note in ci/Dockerfile.kaniko-act.
