Get the global maintenance page GET

Returns whether panel-wide maintenance mode is on, and the global page shown for services without their own. Needs `settings.view`, which owners and admins hold. Available to MCP clients and the assistant.

Set a service's maintenance page POST

Turns a service's maintenance mode on or off and sets its own page or message. Fields left out keep their value; html null falls back to the global page. Takes effect on the node right away, without a deploy. Needs `services.edit` on the service (a grant on its project covers it). Available to MCP clients and the assistant.
