shankar0123 2025275b43 domain, migrations: ApprovalRequest type + issuance_approval_requests + RequiresApproval
Rank 7 of the 2026-05-03 Infisical deep-research deliverable, commit 1 of 4
(cowork/rank-7-approval-workflow-primitive-prompt.md). The four-commit
chain ships the issuance approval-workflow primitive (request → human review
→ CA call) closing the two-person integrity / four-eyes principle
procurement gap for PCI-DSS Level 1, FedRAMP Moderate / High, SOC 2
Type II, and HIPAA-regulated PHI deployments.

This commit lands ONLY the foundation — schema, types, repository
interface, postgres implementation. No service / handler wiring yet.
The four-commit shape is bisectable: the schema can land in production
behind a flag (via the default RequiresApproval=false on every existing
profile) without any operator-visible behavior change until commits 2-4
wire the surrounding workflow.

Existing scaffolding REUSED (not redefined here):
  - JobStatusAwaitingApproval enum value (internal/domain/job.go).
  - JobRepository.ListTimedOutAwaitingJobs (postgres reaper query).
  - Config.Scheduler.AwaitingApprovalTimeout (env-mapped via
    CERTCTL_JOB_AWAITING_APPROVAL_TIMEOUT, default 168h = 7 days).
  - Scheduler.SetAwaitingApprovalTimeout wiring.
