Add Firecrawl marketplace plugin #17529

Problem

ToolJet apps that need public web content currently require custom REST datasource setup.

Proposed solution

Add a Firecrawl marketplace datasource with scrape, search, map, asynchronous crawl start, and crawl status operations. Support Firecrawl Cloud and self-hosted instances, document setup and operations, and add focused tests.

Scope

• Add the marketplace plugin and catalog registration
• Add connection handling for cloud and self-hosted deployments
• Add documentation and tests

I would like to work on this contribution.
