Introducing a new AI-enabled food search capability for Loop. Loop has helped me become a better diabetic and I would love to give back to the community by contributing this new feature for Loop, which I believe will benefit all Loop users.

PROBLEM WE'RE SOLVING: Diabetics often lack nutrition knowledge when estimating carb intake. And we need that knowledge when we’re making dosing decisions, especially when eating out at restaurants - this knowledge is the single most important tool we have to improve our Time in Range and A1C. Loop's Food Search feature uses barcodes and AI analysis to provide accurate nutrition information and advanced diabetes management recommendations.

NEW FEATURE'S IMPACT: The Food Search system is a comprehensive food analysis and nutrition tracing solution integrated into Loop for improved diabetes management. It provides multiple search options including text, barcode scanning, and AI-powered image analysis that produces comprehensive nutrition data and dosing suggestions via diabetic notes. With Food Search, we can enter a meal bolus with MUCH greater accuracy which should improve Time in Range and A1C. The AI-analysis engine can even read menus (in multiple languages) and provide guidance for dosing.

Review the docs in “/Loop/Documentation/FoodSearch 2.0 Docs/” for comprehensive documentation for Loop's Food Search functionality, including AI-powered nutrition analysis and advanced diabetes management recommendations. API setup guides are provided so the user can enter their personal AI API keys to enable AI food analysis.

This new PR (Food-Search 2.0) fixes compatibility bugs from the initial commit and adds Advanced AI Analysis including FPU analysis, and Dynamic Dosing recommendations.

<I will post new screenshots here after submitting this PR>
To prevent breaking Live Activities customizations
Added xcodeproj/project.pbxproj to .gitignore
fixed build errors caused by AbsorptionTimePickerRow function
- Red X delete buttons in Food Details so users can adjust what food items they plan to eat and not eat
- Automatic nutriments total & absorption time recalculations when items are deleted
included accidentally so I'm removing it. should remain unchanged.
