fix: strip main-panel TLS cert file paths when sending inbound to remote node (#4339)

When the main panel creates an inbound assigned to a remote node,
the wireInbound helper sends StreamSettings as-is, including
certificateFile/keyFile paths that only exist on the main panel's
filesystem. The remote node's Xray then fails to load them and crashes.

This adds sanitizeStreamSettingsForRemote() which strips file-based
cert paths before forwarding to a remote node. Inline certificate
content (certificate/key) is preserved unchanged.

Closes #4335
