FRE-4533: Merge apps/{api,web,mobile} and shared-db into ShieldAI repo

Merge FrenoCorp apps into ShieldAI packages/:
- packages/api: merged routes (notifications), middleware (auth, rate-limit, error, logging), config, services (darkwatch, spamshield, voiceprint), tests
- packages/web: new SolidJS web app stub
- packages/mobile: new SolidJS mobile app stub
- packages/shared-db: new Prisma DB package (separate from existing packages/db)
- pnpm-workspace.yaml: restored (apps/* removed, already covered by packages/*)

Next: reconcile packages/shared-db with packages/db, and fix server.ts correlationRoutes import
