feat(user): a random greeting on each drawer open

The greeting row picks one at random from ~/.config/quickshell/greetings,
one per line with {user} for the login name, # comments and blank lines
skipped; without the file, five built-in ones. The row is rebuilt on every
drawer open, so the file is read then with no watch, and the last pick is
kept in User.js, a shared .pragma library, so the same greeting never
shows twice running.
