Add KiCad API v2, orderdetail export control, EDA status indicator, BOM improvements

- Add KiCad API v2 endpoints (/kicad-api/v2) with volatile field support
  for stock and storage location (shown but not saved to schematic)
- Add kicad_export flag to Orderdetail entity for per-supplier SPN control
  (backward compatible: if no flag set, all SPNs exported as before)
- Add EDA completeness indicator column in parts datatable (bolt icon)
- Add ?minimal=true query param for faster category parts loading
- Improve category descriptions (use comment instead of URL when available)
- Improve BOM importer multi-footprint support: merge entries by Part-DB
  part ID when linked, tracking footprint variants in comments
- Fix KiCost manf/manf# fields always present (not conditional on orderdetails)
- Fix duplicate getEdaInfo() call in shouldPartBeVisible
- Consolidate supplier SPN and KiCost field generation into single loop
