Fix CLEAN_INSTALL to wipe dotfiles too

CLEAN_INSTALL now removes dotfiles (e.g. .env) along with other files, using `find -mindepth 1 -delete` instead of `rm -rf *`. Update scripts for affine, nametag, and postiz are updated to explicitly back up and restore .env (via create_backup/restore_backup or cp) BEFORE the build step that sources it, rather than relying on the wipe preserving dotfiles.
