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 Co-Authored-By: Paperclip <noreply@paperclip.ing>
