fix: resolve dashboard OpenAPI integration issues

- FCRs & Transfer to Laying: add ExampleResponse field to routeMeta and
  inject example payloads into OpenAPI 200 responses for list and detail
  endpoints so dashboard consumers have concrete response shapes to work with

- Chick In: enable GET /api/production/chickins/ list endpoint (was
  commented out); add P_ChickinsGetAll permission constant and wire it
  into the route; add OpenAPI spec entry with query params and example

- Recording GET all: fix N+1 query bottleneck (2-3s response time) by
  pre-fetching approved transfer maps per PFK ID in two batch queries
  before the per-recording loop; add evaluatePopulationMutationStateFromCaches
  that uses the pre-fetched maps and caches hasAnyRecordingOnTransferTargets
  results by transfer ID — reducing per-page query count from ~20-40 to ~10-12
