ci(tst-03): disable Windows jobs (act host-mode broken); gate on WINDOWS_CI_ENABLED

act_runner v0.6.1 host-mode on Windows cannot run steps (unresolvable step-script
path) or stage JS actions; Windows containers are impractical for net48/x86/MXAccess.
Skip the windows + live-mxaccess jobs until a working Windows runner exists, so
push/PR checks are the green portable + java jobs. x86 Worker verification stays on
the manual windev worktree process. Re-enable via repo var WINDOWS_CI_ENABLED=true.
