Add Midnight Commander (mc) port and include in all configs

Add mc recipe (v4.8.30) with Redox-specific patch disabling PTY, resolver, subshell, and SFTP/FTP VFS. Build with ncurses against glib. Symlink into recipes/tui/. Add mc package to redbear-desktop, redbear-full, and redbear-minimal configs.

Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent)
