Add layered price lookup and category auto-fill

Browse Source 
- PriceLookupService: eBay live data → saved listing history → AI estimate,
  each result labelled by source so the user knows how reliable it is
- Revalue row: new "Check eBay" button fetches suggestion and pre-populates
  the price field; shows source label beneath (or "No suggestion available")
- Category auto-fill: AutoFillCategoryAsync takes the top eBay category
  suggestion and fills the field automatically after photo analysis or AI
  title generation; dropdown stays visible so user can override
