Fonts + kitty config in the desktop

- tanin-eww: ship Fuji kitty.conf into skel (~/.config/kitty)
- add missing font deps to tanin-eww + tanin-desktop:
  ttc-iosevka-aile (bar's 'Iosevka Aile' UI font) + ttf-nerd-fonts-symbols
  ('Symbols Nerd Font' icon fallback). ttf-iosevka-nerd covers kitty.
- start archiso profile under iso/ (releng-base + overrides; systemd-boot,
  btrfs+snapshots, plymouth, linux-zen, Calamares clone-install)
