CLI Improvements

* Fix #6001 - only use `--notes` in Add/Edit commands to prevent clash with password generator option `-n`.

* Fix #6119 - Send Unicode to clip command; Windows only understands UTF-16 encoding.

* Fix #6128 - `clip` command will default to clearing the clipboard after 10 seconds. To disable clearing set timeout to 0.
