Feature: Add dynamic model selection to ViewReceipt page

Browse Source 
Enhance receipt parsing model selection:
- Fetch available models from LlamaCpp server dynamically
- Show loaded/unloaded status in model dropdown
- Persist selected model to appsettings.json
- Read default model from AI:ReceiptParsingModel config
- Inject LlamaCppVisionClient and IConfiguration dependencies
