v4: the slug and rename fields lose their hints about old links — "Links to the old address keep working." under the dump and playlist link field, and "Their old name keeps leading to them…" under the moderator's rename field, described a server guarantee nobody filling the form needs to read. Only the fields' errors show under them now; UsernameField loses its hint prop. 670 frontend tests pass, tsc and i18n:compile --strict are clean.
