v1.5.6

• Switch off the free plan and the free 7-day trial for new registrations: only paying customers can deploy
• Free plan card shows as currently unavailable and cannot be selected; paid plans drop the free-trial pill
• Review step no longer offers the trial, and no registration can ask for the trial's expire
• ?plan=free links and repo configs asking for the free plan are ignored
• Pricing, marketing pages, FAQ, login modal, CTAs and llms.txt say the offers are currently unavailable
• Apps already on the free plan are unaffected and keep renewing (appsmonitor)
