fix: point docker-compose default at gallery phi-2-chat (#11987)

The quickstart compose file still requested phi-2, which is no longer in
the gallery. Use phi-2-chat instead and fix model preload error wrapping
so discover/install failures report the real error instead of %!w(<nil>).
Keep earlier model failures when discovery fails for another model.
Document the Compose gallery default.

Fixes #11974

 ## Using Compose
 
+The repository's `docker-compose.yaml` installs `phi-2-chat` from the model gallery by default. Change its `command` list to select a different gallery model.

 For a more manageable setup, especially with persistent volumes, use Docker Compose or Podman Compose:
