Publish the two CodeIgniter draft posts (EN+ZH) with OG + banner art

- migrating-codeigniter-iis-to-openlitespeed (engineering): the two fatal errors
  IIS + SSO had been hiding (env() called from Constants.php; parent::__construct
  in a controller) — both only surfaced on the first unauthenticated request
- upgrading-codeigniter-46-to-47 (notes): the two undefined config properties the
  official upgrade guide cannot warn about (Config\App::$permittedURIChars,
  Config\Format::$jsonEncodeDepth)
- both flipped draft:true -> false, pubDate 2026-09-20 -> 2026-09-27 (real publish date)
- generated 1200x630 OG cards + 1600x900 banners for both slugs
- verified before commit: EN+ZH pages build, language switch links both ways,
  listing order stays monotonic on /posts, /zh and the homepage, banner terminal
  panel centred (gapAbove 102 / gapBelow 104) with no overflow

 I maintain a numerology report generator: a CodeIgniter 4 application that takes a birth date and a name, runs them through a numerology engine, and renders a 19-page A4 report. It had run on Windows Server with IIS for years. In September 2026 I moved it to OpenLiteSpeed on CyberPanel, on Linux, on a different domain.

 I upgraded a CodeIgniter 4 app from 4.6.3 to 4.7.4. I read the upgrade guide, checked every documented breaking change against the codebase, and confirmed none of them applied. Then I ran the app and it fataled twice.

 我维护着一个数字命理报告生成器：一个 CodeIgniter 4 应用，接收出生日期和姓名，跑一遍命理引擎，渲染出 19 页 A4 报告。它在 Windows Server + IIS 上跑了很多年。2026 年 9 月，我把它迁到 CyberPanel 上的 OpenLiteSpeed，跑在 Linux 上，换了个域名。

 我把一个 CodeIgniter 4 应用从 4.6.3 升到了 4.7.4。我读了升级指南，把每一项文档化的破坏性变更都对着代码库核了一遍，确认没有一项影响到我。然后我跑了一下应用，它致命崩溃了两次。
