Hardcode Firecrawl API endpoint, drop FIRECRAWL_ENDPOINT config

Firecrawl has a single public API at https://api.firecrawl.dev/v2.
The endpoint was configurable but never varied across environments,
so hardcode it as a package-level const and remove the Endpoint
field from FirecrawlConfig and all downstream wiring (bootstrap,
Helm chart, probod, vetting, cookiebanner).
