feat(oci): GPU selection per host and per image, one notification per update, and App tab for stack containers

- Immich asks what runs its video and its recognition in one menu, in both
  modes, and gives the GPU to the server and to Machine learning; AMD uses ROCm
- Frigate, Ollama, llama.cpp, Faster Whisper and Piper take the image built
  for the chosen GPU
- The acceleration menu offers only what the host can run
- An update or a recreation sends one notification with its result instead of
  the stop, backup and start of each container
- A private bridge with nothing connected is not reported as down
- Secondary containers of a stack appear in the App tab with their version and
  logo; Secure Gateway shows the same update state in both views
- A mistyped value in the wizard asks the same question again
