fix(settings): sort the contributors list chronologically (#700)

* fix(settings): sort the contributors list chronologically

The Settings → System contributors list rendered the array in raw
insertion order, so Psychotoxical (since v1.0.0) showed up last and
hand-maintained ordering drifted over time.

Sort on export instead: ascending by the `since` app version (reusing
isNewer), tie-broken by the first-contribution PR number. The list
stays correctly ordered regardless of where new entries are inserted.

* docs(changelog): add entry for contributors list sort fix (#700)
