CLEANUP: cli: rename the last few "stats_" to "cli_"
There were still a very small list of functions, variables and fields called "stats_" while they were really purely CLI-centric. There's the frontend called "stats_fe" in the global section, which instantiates a "cli_applet" called "<CLI>" so it was renamed "cli_fe". The "alloc_stats_fe" function cas renamed to "cli_alloc_fe" which also better matches the naming convention of all cli-specific functions. Finally the "stats_permission_denied_msg" used to return an error on the CLI was renamed "cli_permission_denied_msg". Now there's no more "stats_something" that designates the CLI.
