fix(network): accept-request/reject-request param mismatch broke connection requests

Web5ConnectedNodes sent { request_id } but the backend only read
params.id, so accepting/rejecting a connection request always failed
with 'Missing required parameter: id'. Frontend now sends id; backend
accepts both spellings for older deployed UIs.
