fc-updater: bump image to v202605301642-296f350-rework (ADR-179 rework live)

Deploy the current FlowerCore.Updater main (PRs #52-#61) to prod: MSI-first
packaging, beta gating + per-install tokens, interactive+bearer Authentik OIDC,
native installer apply, and the .fcsetup.exe retirement (DropReleaseInstallers
migration runs on the now-empty DB). Image pre-imported to rke2-server + agent1.
