fix: restore dashboard dev CI and Immich mobile uploads

- Change deploy-dev workflow runner from ubuntu-latest to nas
  Fixes: CI failing to access /volume1/docker paths

- Add missing immich-machine-learning service to compose
  Fixes: Mobile photo uploads failing due to ML model download timeouts
  - Add 10min timeout for model downloads (MACHINE_LEARNING_REQUEST_TIMEOUT=600)
  - Add 4GB memory limit to prevent OOM during model loading
  - Mount model-cache volume for persistent model storage
  - Add health check and proper logging

Impact: Restores dev deployment pipeline and mobile photo backup functionality
