chore: Remove Firecrawl deployment - pausing until platform infra is ready

Removing Firecrawl ArgoCD application and all manifests. The deployment
was failing due to missing container images that need to be built from
source. This requires platform infrastructure we don't have yet.

Will return to Firecrawl deployment after Harbor registry and Tekton
pipelines are deployed and configured.

Note: ArgoCD also needs a thematic EPCOT name at some point.
