Found 20 errors in 11 files (checked 1199 source files)

Run mypy 1.12.0 against the 1,199 checked source files and reproduce the 20 errors listed in monai/data/utils.py, monai/transforms, monai/metrics, monai/bundle, monai/apps, and tests/test_resample_backends.py. Read the reported lines and their surrounding type annotations first; done means the listed type-checking errors are resolved without breaking the relevant tests.
