Replace inline regex path/URL normalization in resolver.py and
missing_browser_methods.js with the existing shared helpers:
- core/resolver.py: normalize_workflow_download_url now uses
prepare_remote_size_probe_url from type_utils instead of a local
huggingface-specific regex substitution.
- web/resolver/views/missing_browser_methods.js: path identity
generation now uses normalizePathIdentity from html_utils.js rather
than ad hoc replace/trim/lowercase logic.
This keeps normalization behavior consistent across the codebase and
removes duplicated regex patterns.
