feat(etl-cache): route all file-based sources through the parse cache

Every file ingestion path (Dropbox, Google Drive / Composio Drive, OneDrive,
local folder, Obsidian, and the legacy upload handlers) now parses via the
extract_with_cache facade instead of calling EtlPipelineService.extract
directly, so identical bytes are deduplicated globally regardless of source.
vision_llm is passed through, keeping the existing cacheability gate intact.
