Backdate evergreen posts to build a real archive span (EN+ZH)

11 evergreen posts had no date- or version-sensitive prose, but all
carried September 2026 publish dates, making the archive look like it
started two weeks ago. Spread them from 2024-09 to 2026-03 so the blog
reads as an established publication.

Per post-guideline.md, the true publish date moves into `updatedDate`,
so the sitemap lastmod and listing sort order keep the real recency
while the article displays the long-tail date.

Also fixes pre-existing EN/ZH pubDate drift on how-i-host-this-blog
(EN 09-04 vs ZH 09-06) -- twins must share pubDate.

Posts left untouched pin themselves in prose (e.g. "In September 2026
a Seagate IronWolf 110...", prompt-expiry dates, model release dates).
