fix(manager): migrate 4 endpoints GET→POST for CSRF hardening

Align with Comfy-Org/ComfyUI-Manager#2818 (CSRF Content-Type gate).
Convert START_QUEUE, UPDATE_ALL, UPDATE_COMFYUI, REBOOT to POST with
body=null and preserved query params where present. Request shape is
compatible with both the current GET backend and the upcoming
POST-only backend: body=null + axios default application/json header
is explicitly allowed by the backend's reject_simple_form_post gate
(only x-www-form-urlencoded, multipart/form-data, text/plain are
rejected).
