[FEATURE] : Support importing WSL from local Docker images

[Fengqiv]

Is there an existing issue for this?

• I have searched the existing issues

Problem?

WSL2-Distro-Manager currently supports importing WSL distributions from Docker images pulled from docker.io, which is very useful.

However, it does not support importing from locally available Docker images (e.g. images already built or loaded via docker load).

This limitation makes workflows less efficient in offline or local development scenarios.

Solution

Add support for importing WSL distributions from local Docker images, in addition to remote docker.io images.

Allow selecting a local Docker image (by name / tag / image ID)
Use the local image instead of pulling from registry
Reuse existing import pipeline used for docker.io images
