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.
