Composer: sort of "normalize" the file

Well, mostly (scripts are not alphabetized, but still grouped by task).

Note: this is done as a one-time only action. The normalize script will **_not_** be run in CI to enforce normalization.

Style has been standardized to `--indent-style=space --indent-size=4`.
