Initial commit: UOMysticmoon backend (Express + MariaDB + JWT)

- Layered API (router -> controller -> model -> db), serverlinkr pattern
- Public / auth / admin route groups; posts, wiki, settings, users, activity models
- JWT httpOnly-cookie auth (Secure auto-detected: LAN HTTP + Pangolin HTTPS)
- Site LIVE/MAINTENANCE mode with admin preview bypass
- Dual file+console logging (info/warn/error/debug) + HTTP access logs
- Docker Compose (app + MariaDB), schema.sql + seed, .env.example
- Verified end-to-end against MariaDB (27/27 smoke checks)
