Follow-up to #1932, addressing the two points in @yarikoptic-gitmate's review.

• Test the Python dandi.validate._core.validate() API with missing NWB paths passed as both str and Path. The existing CLI test stops in Click before reaching this code.
• Clarify that find_dandi_files() is a generator: it checks requested paths on first iteration, before yielding a file. Add a versionchanged note for the missing-path behavior.

I left upload-path handling to #1974 as suggested.

Validation: 11 focused tests passed (new API cases plus existing discovery and CLI cases); flake8 and git diff --check passed. This does not claim a full-suite run.
