What this PR does / why we need it:

FeatureStore.apply(..., objects_to_delete=[...], partial=False) sorts the objects to delete by type, but it had no case for SavedDataset, so saved datasets were silently ignored. Because feast delete <name> deletes through apply(), the CLI printed Deleted SavedDataset <name> while the dataset stayed in the registry.

This PR collects SavedDataset objects from objects_to_delete and removes them with the existing registry.delete_saved_dataset(...), following the same pattern used for validation references. delete_saved_dataset already exists on all registry backends, so no registry changes are needed.

Which issue(s) this PR fixes:

Fixes #7044

Checks

• I've made sure the tests are passing.
• My commits are signed off (git commit -s)
• My PR title follows conventional commits format

Testing Strategy

• Unit tests
• Integration tests
• Manual tests
• Testing is not required for this change

Added test_apply_delete_saved_dataset in test_local_feature_store.py. It registers a saved dataset, deletes it via apply(objects=[], objects_to_delete=[saved_dataset], partial=False), and asserts it is gone. The test fails without the fix.

Manually verified with a local repo that feast delete <saved_dataset> now removes the saved dataset from the registry.

Misc

No docs change needed: the feast delete reference already lists saved datasets as supported.
