starr-openai 255748638c Fix remote environment test fixtures (#22572)
## Why
The Docker remote-env coverage was failing before it reached the
behavior those tests are meant to exercise. The remote-aware test
fixture only registered the remote environment, so tests that
intentionally select both `local` and `remote` could not start a turn.
After that was fixed, two tests exposed stale fixtures: the approval
test was auto-approving under workspace-write, and the remote
`view_image` test was writing invalid PNG bytes.

## What Changed
- Added `EnvironmentManager::create_for_tests_with_local(...)` so tests
can keep the provider default while also selecting `local` explicitly.
- Updated `build_remote_aware()` to use that test-only manager when a
remote exec-server URL is present.
- Changed the remote apply-patch approval helper to use
`SandboxPolicy::new_read_only_policy()` so the test actually exercises
approval caching per environment.
- Replaced the hardcoded remote `view_image` PNG blob with the existing
`png_bytes(...)` helper so the test uses a valid image fixture.

## Validation
Ran these isolated Docker remote-env tests on the devbox with
`$remote-tests` setup:
-
`suite::remote_env::apply_patch_freeform_routes_to_selected_remote_environment`
-
`suite::remote_env::apply_patch_approvals_are_remembered_per_environment`
-
`suite::remote_env::apply_patch_intercepted_exec_command_routes_to_selected_remote_environment`
-
`suite::remote_env::exec_command_routes_to_selected_remote_environment`
- `suite::view_image::view_image_routes_to_selected_remote_environment`

All five pass.
