[split-required] [guardrail-change] Enforce 500 LOC budget across all services

Install LOC guardrails (check-loc.sh, architecture.md, pre-commit hook)
and split all 44 files exceeding 500 LOC into domain-focused modules:

- consent-service (Go): models, handlers, services, database splits
- backend-core (Python): security_api, rbac_api, pdf_service, auth splits
- admin-core (TypeScript): 5 page.tsx + sidebar extractions
- pitch-deck (TypeScript): 6 slides, 3 UI components, engine.ts splits
- voice-service (Python): enhanced_task_orchestrator split

Result: 0 violations, 36 exempted (pipeline, tests, pure-data files).
Go build verified clean. No behavior changes — pure structural splits.
