Initial import of slot-ss.com (gnuboard5 + Eyoom + YoungCart) for migration

Original PHP source rsync'd from production server (slot-ss.com) on 2026-04-27.
Excluded from import:
  - data/editor (74GB user uploads), data/file (8.5GB attachments)
  - data/member_image, vendor/, db100up/, caches/sessions/logs/tmp

Includes:
  - 11,636 files, ~206MB source code (gnuboard5 v5.6.6, Eyoom builder, YoungCart 4)
  - 28 plugins (bacara, chatbot, cron, swiunApi, sns, sms5, ...)
  - Active theme: eb4_maga_005 (Eyoom magazine layout)
  - Local Docker dev stack (PHP 7.4 + Apache + Redis + MariaDB) under docker/
  - PostgreSQL migration setup (pgloader configs) under db/
  - Architecture/migration docs under docs/

Single non-source patch: src/config.php now reads G5_DOMAIN_OVERRIDE env var
so the local Docker stack can serve at http://localhost:8088 without touching
the production constant. Falls back to https://slot-ss.com when unset.
