Add PHP Media API scaffold and Docker configs

Initial project scaffold for a PHP Media API including routing, controllers, models and services under api/ (Router, Media/Cast/Image/Settings controllers, models, database/bootstrap files and automatic docs service). Adds Docker support (Dockerfile, docker-compose.yml, DOCKER_README.md, php-custom.ini), .htaccess for pretty URLs, API documentation and example payloads (API_EXAMPLES.md, api/README.md, api_examples/*.json), image handling service and logging, plus a comprehensive .gitignore. This commit provides a runnable development environment and example requests to get the API up and tested quickly.
