Was seeing "upload failed: 413" on mesh attachment sends between
federated nodes — a ~7MB image becomes ~10MB base64 in the
typed_envelope wire and hit the 10m client_max_body_size on
/archipelago/, /content/, and /dwn/. Bumped those six locations
(two per server block, regular + HTTPS) to 256m so modern
attachments/blobs don't trip the proxy. /rpc/ stays at 1m —
internal JSON-RPC calls are small and don't need the headroom.
Applied to all 4 fleet nodes live; ISO source config updated so
fresh installs get the same limits.
