Restore MiniMax media routing parity across image and video flows

The server now keeps portable image ratio normalization, enforces documented Seedream size presets, routes MiniMax img2img through generations-style payloads, and submits Hailuo video variants through the video generations API with proper reference-image handling. Constraint: The deployed test chain relies on popiartServer as the lowest-risk place to adapt provider-specific routing without broad newapi changes Rejected: Expand newapi relay modes for every MiniMax image/video branch | larger blast radius than needed for the verified server-managed flows Confidence: high Scope-risk: moderate Reversibility: clean Directive: Keep MiniMax-specific media routing in popiartServer unless upstream newapi adapters are upgraded to the same contract Tested: go test ./internal/server -run TestInferRouteKeyForModelRecognizesViduAsVideo|TestGenerate|TestResolve|TestSubmitMiniMaxVideoTask|TestExecuteImageToImageJobUsesGenerationsPathForMiniMax|TestExecuteImageToVideoJob|TestResolveVideoReferencesSupportsImagesArray Not-tested: Full PopiNewAPI unit suite (blocked earlier by external module checksum drift in local checkout)
