Propagate firecrawl and tracker-mapping config to bootstrap and Helm

Group firecrawl-endpoint and firecrawl-api-key under a nested firecrawl
config key. Add env var mappings (FIRECRAWL_ENDPOINT, FIRECRAWL_API_KEY,
SEARCH_ENDPOINT, AGENT_TRACKER_MAPPING_*) to the bootstrap builder with
test coverage. Wire the new values through the Helm chart (values,
deployment, secret, production example).
