Egg prices today, by county

Wholesale/retail prices, history, best market, and layer economics.

Not built yet

Eggs are a product, not a crop - the price infrastructure this needs (ProductMarketPrice, same as BeiFarm uses for crops) exists on the backend, but no egg price observations have been reported into it yet.

→Confirm/seed an 'Eggs' CropProduct entry so GET /knowledge/products/{id}/market-prices has something to return
→Reuse BeiFarm's price-page pattern once real egg price data exists - this is mostly a data-availability gap, not a missing feature
→Link 'layer economics' to PoultryCalculator's egg production and layer profitability calculators instead of rebuilding them here
