We finished ticket #55, adjusted the CICD to deploy if the VM is shut…

[JonathanPschl]

Summary

Closes #55 #56 . Adds recipe → grocery-list merging across the client and grocery-service,
hardens the Gen AI categorization output, and makes the Azure deploy resilient to a
powered-off VM.

Changes

Recipe merging (#55)

• grocery-service: new POST /api/grocery-list/merge endpoint. Reads the selected
  recipes, delegates dedup/quantity-summing to gen-ai's /api/ai/merge, and persists the
  result as a new grocery list linked to its source recipes via grocery_list_recipes.

• client: generated dishes are now saved as a recipe only; grocery lists are created
  later by selecting 2+ recipes on the Recipes page and merging. Adds a merge bar with
  checkboxes, success/error banners, and a "saved to Recipes" confirmation on Home.

Gen AI categorization fixes

• Prompt now generates ingredients for a bare dish name (never returns an empty list)
  and emits the coarse category tokens verbatim.
• temperature: 0 for deterministic, consistent categorization.
• GroceryItemMapper: alias table maps legacy/drifting category labels (e.g. "Dairy & Eggs",
  "Dry Goods & Pasta") onto the enum instead of silently collapsing to OTHER.

CI/CD & infra

• deploy-azure.yml: az vm start step (idempotent) so deploys work when the VM was
  deallocated to save cost.
• outputs.tf: expose resource_group_name / vm_name for the start step.
• site.yml: defer fact-gathering until after wait_for_connection so Ansible doesn't fail
  SSHing into a just-booted host.
