Validate partial model-selection patches against the target selection.

ModelSelectionPatch allows instanceId to be omitted, and patch application preserves the target's current instance in that case. filterSharedServerPatch compares provider instances using the source instanceId, while isModelSelectionProviderEnabled checks the target's effective selection. These checks can inspect different providers, so a partial model or options patch can be dropped incorrectly or applied to the wrong provider. Compare the source provider with the target effective provider, and add a test with different source and target selections.

minimal, and validate.

In `@packages/client-runtime/src/state/sharedSettings.ts` at line 69, Update
filterSharedServerPatch to resolve the target’s effective instanceId when
ModelSelectionPatch.instanceId is omitted, then compare the source provider
against that target provider consistently with isModelSelectionProviderEnabled.
Preserve the existing behavior for explicit instanceId values, and add coverage
for different source and target model selections with a partial patch.
