fix(node): node.toml's transfer pools reach the transport

The daemon built the defaults dict for `Roster.node_settings` by hand and
left out `max_concurrent_downloads` and `max_concurrent_uploads`. Absent
from the dict, both resolved to None, were assigned back onto the config,
and the transport skipped them — so node.toml was parsed, validated, and
then replaced by `transfers.py`'s own 8. Invisible to anyone who left the
value at 8, which is the value the template suggests.

There were three copies of that dict and they all disagreed: node_status'
was missing those two and `max_upload_gb` besides. One builder now,
`config.node_settings_defaults`, and the resolver's key list is a class
attribute the tests hold it to, along with the writer's.

1429 passed against a baseline of 1423; the two new behavioural tests fail
with the builder reverted.
