fix: resolve integration issues after phase branch merges

- Register errandProcedures in appRouter (was defined but never spread)
- Fix nullable projectId guard in errand delete/abandon procedures
- Add sendUserMessage stub to MockAgentManager in headquarters and
  radar-procedures tests (AgentManager interface gained this method)
- Add missing qualityReview field to Initiative fixture in file-io test
  (schema gained this column from the quality-review phase)
- Cast conflictFiles access in CLI errand resolve command
