- PR #140308: MCP OAuth: an unset ${VAR} client ID is treated as unset on every flow, never sent or stored (salvage #108269, inspired by Cursor)

A bug caused unresolved ${VAR} placeholder strings to overwrite valid OAuth client identities in MCP configurations. Fixes prevent placeholder values from being treated as or written over real OAuth client credentials.
