feat: WordPress migration support — upload existing site files

- Add two deployment modes for WordPress: Fresh Install vs Migrate Existing Site
- Fresh Install: vanilla WordPress from official image (existing behavior)
- Migrate: upload ZIP with wp-content/ (themes, plugins, uploads), wp-config.php, .htaccess
- Custom entrypoint merges staged wp-content into PVC on first container run
- Add init container for fresh WordPress builds (empty source context for Kaniko)
- Increase upload limit to 200MB for WordPress sites
- Add PHP upload limits (64MB) and memory config in WordPress Dockerfile
- Update deploy page review step to show WordPress mode info
- All UI in English
