style(config): Reformat Emacs Lisp code for consistency

Standardize formatting across multiple init files: expand
single-line use-package keywords onto separate lines, fix
indentation, remove outdated comments, and clean up whitespace. Also
adds mc/keymap <return> binding and improves fcitx5 startup logic in
EXWM.
