- Standardized the web crawler to use Scrapling exclusively, removing Firecrawl entirely.
- Updated the crawler's location to `app/proprietary/web_crawler/connector.py` under a non-Apache-2 license boundary.
- Refactored the `WebCrawlerConnector` to eliminate the Firecrawl API key dependency, simplifying the interface for crawling URLs.
- Adjusted related components to accommodate the new structure and ensure successful crawl outcomes are properly handled.
- Updated documentation to reflect these changes and the new implementation status.
Apply the same rename to surfsense_backend/tests: workspace_id fields/vars,
Workspace* classes/schemas, table name searchspaces -> workspaces in raw SQL,
and the API URL spellings -> /workspaces. Preserves the carve-out wire literals
tests assert (Celery task names, OTel key "search_space.id").
