Pete 8a68f3571c feat(api): add POST /v1/images/upscale endpoint (#10227) ...

* feat(api): add POST /v1/images/upscale endpoint

Add a new image upscaling endpoint that accepts a source image and
returns an upscaled version. Supports selectable upscaler models
(e.g. realesrgan) and a configurable scale factor (2x or 4x).

- backend.proto: add UpscaleImage RPC and UpscaleImageRequest message
- pkg/grpc: implement UpscaleImage in Backend interface, client, server
  and embed shim
- core/backend/upscale.go: new backend helper (mirrors ImageGeneration)
- core/http/endpoints/openai/upscale.go: new multipart/form-data handler
- core/http/routes/openai.go: register POST /v1/images/upscale
- core/http/auth/features.go: gate upscale routes under FeatureImages
- backend/python/diffusers/backend.py: implement UpscaleImage — uses
  diffusers upscale pipeline when loaded, falls back to Lanczos resize

* fix(grpc): add UpscaleImage stub to Base backend

All Go backends embedding Base now satisfy the AIModel interface
without needing to implement UpscaleImage explicitly.

* fix(images): complete upscale endpoint integration

Store generated upscales under the served images directory, validate scale factors, document and advertise the endpoint, and add a functional Stable Diffusion x4 gallery model.
