Subject: feat(node): editable node settings in the Node page (D5)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Expose invite_ttl_hours, pair_ttl_hours, device_request_ttl_minutes,
max_concurrent_streams and transcode_incompatible_video in the Node
management panel. Changes are applied immediately via roster.db and
written back to node.toml so they survive a DB wipe. On startup,
roster overrides take precedence over node.toml defaults.

Draft v6 §2.11 documents the design; MNP gains node_settings_set /
node_settings_set_ack for the browser path.
