Text-file exports can carry RFC 1123 dates ("Fri, 14 Feb 2025 15:20:09 GMT"),
which sort on the weekday name and fall outside --fromDate/--toDate
comparisons. PostDates.Normalize converts them on every PostDate write path
(AddPost, UpsertPostFromTextFile, UpdatePostContentFields).
normalize-postdate.sql fixes the 4 existing rows.
