Inline comments:
In `@docs/studio/index.mdx`:
- Line 52: Update the Virtual Models description in docs/studio/index.mdx (line
52) to say the default backend model is shown “when configured.” Apply the same
optional wording to the “Default model” description in
docs/studio/virtual-models.mdx (line 32), and note there that request middleware
can handle routing when default_model_entity is omitted.

In `@docs/studio/virtual-models.mdx`:
- Line 9: Update the Virtual Models documentation to describe autoprovisioned
models as controller-managed, rather than platform-created, since users can set
the field manually to opt into controller cleanup. Apply this wording
consistently at docs/studio/virtual-models.mdx lines 9 and 33.
