feat(examples): add deployment examples for common use cases

Add 5 example configurations covering popular deployment scenarios:

1. minimal.yaml - Quick start with ephemeral storage
2. production.yaml - Production setup with PVC and resource limits
3. hardware-acceleration.yaml - GPU transcoding (Intel QuickSync)
4. ingress-tls.yaml - External access with HTTPS and cert-manager
5. network-policy.yaml - Secure deployment with network isolation

Includes comprehensive README explaining usage and combinations.
