Clone Repo could only clone under ~/codeman-cases. POST /api/cases/clone now takes an optional path (parent folder plus case name) and the Clone tab gets a Clone into a custom folder option with a Browse button, mirroring Create in a custom folder. The path is judged by prepareNewCasePath, the clone is registered as a linked case, the option is admin-only in multi-user mode, and an existing target folder is refused.
