Add dvm-textgen and dvm-imagegen to NIP-90 DVM section

Two Go implementations of NIP-90 Data Vending Machines with Lightning payments:
- dvm-textgen: kind 5050 text generation (Llama 3.3 70B via Groq)
- dvm-imagegen: kind 5100 image generation (FLUX.1 Schnell)

Both use LNbits for Lightning invoicing, announce via NIP-89,
and listen on major relays (damus, nos.lol, primal).
