Initial commit: Freepik REST API

FastAPI async wrapper for Freepik cloud AI API supporting image generation
(Mystic, Flux Dev/Pro, SeedReam), video generation (Kling, MiniMax, Seedance),
image editing (upscale, relight, style transfer, expand, inpaint), and
utilities (background removal, classifier, audio isolation). Includes async
task tracking with polling, Docker containerization, and Gitea CI/CD workflow.
