user.set_password: change your own password; TUI "Byt lösenord"v0.1.68

Needs the current password (wrong ones rate limited like logins) and a
password session, requires at least 10 characters, closes the user's
other sessions and is audited without secrets. The TUI main menu gets
"Byt lösenord" with masked prompts; ^R keeps working with the new
password. Masked prompt buffers are wiped before they are freed.
