Three bugs in CLI-to-config conversion:
1. Comma-separated -F nodes shared Connector/Dialer/Metadata pointers
due to struct value copy; add deep-copy helpers per node.
2. Port-range-expanded -L services shared Handler/Listener/Metadata
pointers; deep-copy per service so metadata mutations don't cross-talk.
3. buildServiceConfig's ?auth= query param unconditionally overwrote
URL-embedded auth; buildNodeConfig used fallback-only. Align both
on URL-auth-first semantics (query param as fallback).
