[Fix] Fix HTML fuzzy cache key to prevent overwriting text cache

HTML fuzzy hashes were incorrectly cached using the standard text fuzzy
cache key via fuzzy_cmd_set_cached(), causing HTML hashes to overwrite
text hashes for the same part. Now HTML fuzzy uses the dedicated
html_cache_key for both read and write operations, preventing cache
conflicts and ensuring proper retrieval of HTML fuzzy data.
