Deferred distribution: pause/resume controls with reason capture and audit

[greatest0fallt1me]

Description

Ops needs to pause a scheduled distribution mid-flight (e.g. on liquidity concern) and resume it later without losing state. Add pause/resume endpoints with reason capture and audit event on each transition.

Requirements and context

• Must be secure, tested, and documented
• Should be efficient and easy to review
• Relevant code: src/services/distributionScheduler.ts, src/routes/distributions.ts
• Pause reason must be non-empty

Suggested execution

• Fork the repo and create a branch
• git checkout -b feat/distribution-pause-resume
• Implement changes
  • Add state machine transitions with audit
  • Add API endpoints with RBAC
  • Emit distribution.paused_seconds histogram
• Validate security and correctness assumptions

Test and commit

• Run tests
  • npm test
• Cover edge cases
  • Resume of an unpause is idempotent
• Include test output and notes

Example commit message

feat: pause/resume for deferred distributions

Guidelines

• Minimum 95 percent test coverage
• Clear documentation
• Timeframe: 96 hours
