Rename the confusing ricecooker.utils.utils module path

The module ricecooker/utils/utils.py is imported as ricecooker.utils.utils — a stutter that reads poorly and gives no hint of its contents (path helpers like extract_path_ext, copy_file_to_storage, get_hash, etc.).

We should rename it to something meaningful (e.g. ricecooker.utils.paths / ricecooker.utils.storage, split by concern if warranted) and update all import sites.

Follow-up split out from review discussion on #690 (#690), where utils.utils surfaced again in archive_assets.py. Deferred there to avoid unrelated churn.

Plan: Replace the meaningless grab-bag module ricecooker/utils/utils.py with concern-named modules and relocate the one domain-specific item, updating every import site.

• Extract validators.py
• Extract paths.py
• Extract storage.py
• Relocate VideoURLFormatError and delete utils.py
