FRE-4529: Transfer ShieldAI code from FrenoCorp repo

Transferred ShieldAI-related files mistakenly placed in ~/code/FrenoCorp:
- Services: spamshield (feature-flags, audit-logger, error-handler), voiceprint (config, service, feature-flags), darkwatch (pipeline, scan, scheduler, watchlist, webhook)
- Packages: shared-analytics, shared-auth, shared-ui, shared-utils (new); shared-billing, jobs supplemented with unique FC files
- Server: alerts (FC version newer), routes (spamshield, darkwatch, voiceprint)
- Config: turbo.json, tsconfig.base.json, vite/vitest configs, drizzle, Dockerfile
- VoicePrint ML service
- Examples

Pending: apps/{api,web,mobile}/ structured merge, shared-db/db mapping
