Add Health Readiness Probes and GDPR Self-Service Export

Task: Add Health Readiness Probes and GDPR Self-Service Export

Overview

Health module needs live/ready probes for ops, and users need self-service data export/delete for GDPR-style compliance.

---

Goals

• GET /api/v1/health/live — process up (200)
• GET /api/v1/health/ready — PostgreSQL check via Terminus (503 if down)
• GET /api/v1/users/me/export — JSON of profile, preferences, subscriptions (no password hash)
• DELETE /api/v1/users/me — soft delete + revoke sessions

---

Deliverables

• Health controller (rate-limit exempt)
• GDPR/export service + audit on self-delete
• Integration tests for ready probe + export

---

Acceptance Criteria

• /health/ready returns 503 when DB unreachable (mocked)
• /health/live returns 200 without DB check
• Export excludes password hashes/tokens
• Self-delete soft-deletes user, revokes refresh tokens, returns 204
• Deleted user cannot authenticate
• At least 8 tests
