Merge branch 'claude/datetime-format-consistency-b68faa' into master

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.

+- **`PostDate` is `yyyy-MM-dd HH:mm:ss GMT`** — UTC, as the Tumblr API sends it, unlike

 - `HasImage = 1` on 14,026 rows. It records that the post *had* a picture, not that a
   usable URL was kept, so it is not a reliable predictor that anything will render.
 - `PhotoURL` is largely unused; in practice the image markup lives inside `Body`.
