[EXTRACT] RecipeService - Rip recipe operations from monolith

[democratize-technology-code-reviewer]

🔪 Extraction Target

Extract all recipe and meal planning operations from the 19,843-line index.mjs into a focused RecipeService class. Clean extraction. No compatibility nonsense.

📁 Methods to Extract

// All of these get ripped out and moved to RecipeService
getRecipes()
getRecipe()
createRecipe()
updateRecipe()
deleteRecipe()
getRecipeFulfillment()
addRecipeToMealPlan()
getMealPlan()
consumeRecipe()
// ... and any other recipe-related methods

🎯 Definition of Done

• Create services/RecipeService.js extending BaseService
• Extract ALL recipe methods from index.mjs
• File size < 500 lines (enforced by linter)
• All existing tests pass WITHOUT modification
• Add JSDoc comments for each method
• No deprecated methods or compatibility layers
• Update all imports/references in index.mjs
• Zero regression - identical functionality

⚡ Implementation

// services/RecipeService.js
export class RecipeService extends BaseService {
  async getRecipes() {
    // Direct copy from index.mjs - no changes
  }
  
  async getRecipe(recipeId) {
    // Direct copy from index.mjs - no changes
  }
  
  async consumeRecipe(recipeId, servings) {
    // Direct copy from index.mjs - no changes
  }
  
  // ... rest of recipe methods
}

🚫 NOT in Scope

• Backward compatibility
• Deprecation warnings
• Proxy methods in GrocyClient
• Changing method signatures
• Adding new features

💀 Breaking Changes

Yes. Fix your imports.
