studio: reuse HF cached repo casing to prevent duplicate downloads (#4822)
* fix(studio): reuse HF cached repo casing to prevent duplicate downloads

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Move cache case resolution tests to separate PR

Tests for resolve_cached_repo_id_case and get_model_config case resolution
belong in their own PR to keep this change focused on the runtime fix.

* fix(studio): debug-log HF_HUB_CACHE fallback in path_utils

* Fix stale memoization in resolve_cached_repo_id_case

- Check exact-case path before memo to ensure a newly-appeared exact
  match always wins over a previously memoized variant
- Validate memoized entries still exist on disk before returning them
  to prevent stale results when cache dirs are deleted/recreated

* Minor cleanups for cache case resolution

- Use .is_dir() instead of .exists() for exact-case cache check
  (cache entries are always directories)
- Remove redundant fallback in _detect_audio_from_tokenizer since
  get_cache_path already handles case resolution and returns None
  when the model is not cached
