Implement Workstream F1: me.get and me.setupProfile procedures

- Add me.get procedure returning user profile with needsSetup flag
- Add me.setupProfile procedure for initial profile setup after signup
- Add nonEmptyString/optionalString schema helpers with tests
- Use Web Crypto API (SubtleCrypto) for Cloudflare Workers compatibility
- Use @formatjs/intl-durationformat for duration formatting
- Remove node:crypto dependency from crypto utilities
