fix(firecrawl): correct Docker image registry paths

- Changed from ghcr.io/mendableai/* to ghcr.io/firecrawl/*
- Updated all three services: main API, playwright-service, and nuq-postgres
- Changed tag from v1.0.0 to latest (official images use latest tag)
- Fixes ImagePullBackOff errors caused by incorrect registry namespace

Per official Firecrawl docker-compose.yaml, images are published under
ghcr.io/firecrawl/, not ghcr.io/mendableai/

cluster/applications/firecrawl/chart/values.yaml
