fix(blocks): Add missing error output pins to all Firecrawl blocks (#11256)

Added error output pins to all Firecrawl blocks as standard on the
AutoGPT platform. The base block execution code already handles error
yielding, so no try-catch logic was needed.

- FirecrawlScrapeBlock: Added error output pin for scrape failures
- FirecrawlCrawlBlock: Added error output pin for crawl failures
- FirecrawlExtractBlock: Added error output pin for extraction failures
- FirecrawlMapBlock: Added error output pin for map failures
- FirecrawlSearchBlock: Added error output pin for search failures

Resolves #11253
