Code Review

This pull request updates the image model registry and generation handlers to transition from FLUX.1 and SD3 models to FLUX.2 and SD3.5, while adding support for several new models including Wan 2.6 and NanoBanana. The review feedback highlights a critical omission of the new FLUX.2 models from the image-to-image processing logic and identifies several opportunities to improve the consistency of model naming and the handling of inactive providers within the registry.

This commit is intended to correct the primary image model list.
The next commit will update some platform API specifications, as they use outdated methods.

Thanks @backryun for this great contribution! 🎉 The image model registry refresh with FLUX Kontext / FLUX.2 mappings has been integrated into the release/v3.7.3 branch via a local merge (the GitHub auto-merge had conflicts from other PRs merged earlier). It will be part of the next release. We appreciate your effort!

Merged locally into release/v3.7.3 — closing as integrated. Thank you!
