Set personal git identity, fix zshrc theme, improve bw-ssh service

- config/git/gitconfig: real name, email, and SSH signing key
- config/shell/zshrc: fix typo 'powerlevel10zsh' → 'powerlevel10k'
- config/systemd/bw-ssh-keys.service: depend on graphical-session
  instead of network (ssh-agent starts with session); add explicit
  PATH so bw and jq are found; add RemainAfterExit=yes
  (avoids restart loop on oneshot services)
