switch llama-swap to unified-vulkan image with FLUX.1-dev image generation

- Update deployment to unified-vulkan-2026-05-19 (includes llama-server,
  sd-server, whisper-server in one image)
- Fix binary paths: /app/llama-server -> llama-server (now on PATH)
- Migrate groups -> matrix to allow FLUX to evict the always-on 0.8B model
  when image generation is requested
- Add FLUX.1-dev Q4_K_S model via sd-server
- Configure OpenWebUI image generation to use llama-swap sd-server
- Update renovate versioning regex to treat all unified-vulkan date tags as
  patch updates for automerge
