chore: update telemetry to Auth0 format with dynamic versioning (#773)

## Changes

- Replace Fern telemetry headers (X-Fern-*) with Auth0 standard format
- Use Auth0-Client header with base64-encoded JSON telemetry
- Implement dynamic version reading from package metadata
- Add cryptography unknown license exception to .snyk
- Add client_wrapper.py to .fernignore to prevent Fern regeneration
