Every route accepted a 1 GiB body, and nginx buffers a body to disk before the panel can refuse it: anyone, without an account, could fill that disk with large requests sent slowly and never finished. The one large body is an ISO upload's chunk, 32 MiB (storage_page.js); the limit is now 64 MiB. Checked with nginx and this config: 33 and 64 MiB pass to the panel, 65 MiB is answered 413.
